Candling the eggs: Week two

March 9th, 2014 § 0

Tonight I snuck a peek inside some of the eggs incubating under the broody hen in the garage. It is much warmer tonight than last Sunday, so I felt comfortable taking a few photos to show you the developing chicks. Again, for a candler I just use a Mag-Light flashlight with the end duct taped but for a dime-sized hole. Here’s what the embryos look like at 14 days:

I didn’t candle all the eggs, but I did enough to determine that I have at least a few little Wheaten Ameraucanas (baby Coras) in development. The pale blue eggs are much easier to see into than brown eggs. If you want to see what the embryos look like inside at this stage, click here.

I didn’t make out too much movement, but that’s typical for this stage of development. Each embryo should soon be flipping around in its shell, pointing its head toward the rapidly-shrinking air cell (the bright, clear blue area in egg) in preparation for breaking through it with their egg tooth at hatching.

There are nine possibly viable eggs left under the hen. Props to the still-unnamed broody hen for keeping all these eggs warm during some seriously cold temperatures last week when it was well below freezing on her nest. If all continues to go well, we might have some St. Patrick’s Day chicks!

Drinking and candling

March 1st, 2014 § 1

Last night I drank half a glass of wine and candled the 15 eggs I’d put under a newly broody hen Sunday. What, this isn’t your idea of a rocking Friday night?

Maybe not for most people, but for me candling eggs induces Christmas-morning excitement. There are few things cooler in this world than getting to peek into an intact egg, with nothing more than a flashlight, and see bright red veins, a beating blob of heart and small dark eye. It is a magic trick, a miracle, and all those other things that make me grateful to be along for this wild ride.

Out of fifteen eggs, eight were definitely on the road to becoming chicks. One egg was a big fat question mark, and I magnanimously returned it to the clutch. I suspected five eggs were infertile, and in the interest of self education I risked destroying embryos to crack the eggs into a white bowl to check. All five were totally clear. My instinct and eye must be getting sharper.

I didn’t take any photos of the developing eggs this time because I wanted them to be out in the cold air as little as possible. In fact, I withdrew them from under their mother two at a time, quickly candled them, and then snuggled them into a pan full of clean towels to hold their heat as much as possible. The whole operation was over in minutes. My pipes may have fallen victim to the polar vortex, but my potential chicks shouldn’t. If you want to see candling photos, they’re here.

I have high hopes for this hen as a broody. She’s one of last summer’s olive egger babies, and there’s a 50% chance she is Dahlia’s daughter. I only mention that because broodiness is a genetic trait. The young broody started plucking her breast feathers out a few weeks ago, and then hunkered down on all her flockmates’ eggs, hissing violently at any chicken that got too close. She’s the only broody out of the four I’ve had that’s actually pecked at me when I reached under her, and I take this feistiness as a good sign. I suppose I should name her as she’s definitely distinguishing herself.

I was on the fence about whether to do chicks again, but finally decided that it’s the best part of chicken keeping and costs me nothing. So I moved the broody to a coop in the garage, where she settled immediately despite being moved during the day, having a raucous rooster (Griz) in the coop next door, and me driving the loud and stinky tractor in and out right after the move. She remained steadfast, I set the eggs, and here we are.

I placed four eggs from my Coronation Sussex, two from last year’s olive egger babies, and nine Wheaten Ameraucana eggs from Cora under the hen. I removed all four of the Coronation eggs tonight, which were all infertile, and one Wheaten Ameraucana egg that was one of the oldest I placed, and had also cycled through the refrigerator as I waffled. I find it telling that my Coronation Sussex hen is the only bird that still has luxuriant feathers on her back and all her eggs were infertile. The hens that laid the fertile eggs are all looking a bit sparse back there because of Calabrese’s attentions. Another lesson learned—keep an eye out for “favorite” hens when scouting future mothers.

I just read back through last summer’s pained posts on hatching eggs, and I have to say that after that experience and this, I will never again let a hen set eggs in the middle of the summer. I realize now that the heat was really detrimental, leading to spoiled eggs that burst and contaminated the nest, and to chicks that were born prematurely and deformed. Incubating in the winter is the way to go. Live and learn.

But then again, we’re only five days into the 21-day incubation period, so let’s not count our chicks before they hatch, right?

Update on the broody hens: Candling the eggs

June 28th, 2013 § 2

Today marks the halfway point in the incubation of the chicken eggs. It’s been ten days since I placed them under the hens, and my most respected chicken resource states that eggs incubated under broodies usually hatch in twenty days instead of the 21 days for mechanically  incubated eggs. We shall see. As it is things aren’t looking awesome in the brood coops, and my confidence in the viability of these hatches is waning.

One of the eggs in Oregano’s coop was broken when I checked earlier in the week, and then yesterday I found the broken shell of a Coronation Sussex egg—the prettiest one of the bunch. Boo.

BrokenEggWeb

I don’t know if they are breaking on their own because they are rotten or if she’s cracking (and possibly eating) them. That nest box didn’t smell horribly of rotten egg, so I suspect the egg was fertile when broken. However, I don’t know how many days it would take under the hen for an infertile egg to spoil. So that’s the situation in Oregano’s coop. She’s been getting off the nest, as evidenced by her “deposits” in the cage, and has lost a lot of weight already. Broody hens generally don’t eat much while sitting, and if they do get off the nest their poo has such a strange and horrible smell that it’s enough to gag you just walking into a room with it. Needless to say I remove it as soon as it’s discovered, to keep flies off it and to get it out of my life and into the compost pile.

Over in Dahlia’s coop, I found a major mess in her nest box. One of the olive egger eggs placed under her was broken, and it had made a horrid fermented/cooked mess in the nest. At least five of the ten remaining eggs were coated in dried egg goo. Not good, for several reasons. The incubating egg is a living vessel, and its shell needs to be clean to allow air to pass in to the developing embryo. To seal the pores of the egg could suffocate the embryo.

I was at a loss as to what do. I know the embryos need air, but I also know that to wash an egg is to remove its “bloom” or protective covering that helps keep bacteria out of the egg. In this case, though, I figured washing was probably the lesser of two evil decisions, so I gently scrubbed the dried egg off the dirty eggs.

DirtyEggWeb

Oregano had a few dirty eggs too, so I touched those up as well, trying to just wash the dirtiest areas. Then I cleaned out Dahlia’s stinking messy nest, filling it with clean pine shavings. I made notes in my log of which eggs I washed, which may be telling around hatch day.

Of course I started this project before suiting up with gloves, and the stink that was on those eggs was so strong I couldn’t get it off my fingers all night despite multiple scrubbings and soaking in lemon juice. In all, it was a fittingly disgusting ending to an evening that began by killing a black widow in the crawlspace. Ugh.

Tonight it was time to candle the eggs, which means I shine a light through them to see if they are developing into chicks. I made a candler out of a MagLight flashlight (with fresh batteries) topped by a taped-on piece of cardboard to concentrate the beam and cushion the eggs.

MagLightWeb

Then after dark I headed out to the garage to candle the eggs. All I needed was my candler, my record log and pencil, and a small dish to hold the eggs as I pulled them from the nest. I waited for the garage door lights to go off and began with Oregano’s eggs.

TheSetUpWeb

I removed each egg from under Oregano, enduring a peck on the wrist each time, bless her. I held the egg over the end of the candler, turning it until I could see something, or nothing. Most eggs looked like this, below, with some murky shape with no clearly defined blood vessels but perhaps the hint of a developing eye. Perhaps because many of them are Black Copper Marans eggs, which are dark to begin with and thus more difficult to candle.You can clearly see the air sack at the bottom of the egg.

SomethingWeb

Here’s an egg in which you can see some veins and perhaps a developing eye, right on the line between shadow and light.

MoreSomethingWeb

Here’s an egg, unfortunately one of the two remaining olive egger (Oregano’s) eggs, that I think has no development:

NothingWeb

Here’s a Black Copper Marans egg that appeared very porous. This porosity is thought to be an indication of a poor egg for hatching.

PorousWeb

The clearest picture came from the last egg I candled, a Coronation Sussex under Dahlia. You can definitely see a healthy pattern of veins, and as I watched, I could even see the embryo moving within the shell.

CoronationSussexWeb

I have to admit that holding this egg in my hand, in the dark, and seeing those veins pulse is a pretty freaking incredible feeling. It’s scary, to hold such perfectly planned beauty alive within that fragile shell.

Out of the 20 remaining eggs, there is only one (the olive egger) that I feel I can conclusively describe as not developing. The rest are big question marks, and I am not yet experienced enough to discard any eggs based on my judgement. I feel better about the clutch under Dahlia, my Black Copper Marans, than the clutch under Oregano, my olive egger. But that’s just a hunch. So they will all stay put in the nest, and we will wait the ten more days to see what becomes of them. As you can already tell, a lot can happen in the next ten days. And so I remind myself, and you, dear reader: “Don’t count your chickens until they hatch.”
