I’ve got a bunch of shipped eggs in the incubator and participating on the hatch a long so we are at day 6 today.

My worst eggs had pretty damaged air cells. Some large saddles, one I couldn’t even find, and others that were just gel sort of rolling around but not totally displaced.

I waited until day 3.5 to turn these. Last night I candled and weighed the entire incubator. There’s so dang much information on all sides I just picked the average time I found from 1 to 7 days of no turning.

Anyway all the eggs have great development. A lot of those air cells are solid now. A couple are notttttt so much. There’s still a few jelly and a few that can move.

I’m going to not touch those bad cells again as long as I can wait.


All of this background for a few little questions....

Am I looking for the same weight loss in bad air cell eggs as good? I’ve got a few eggs that are my favorites and I’m weighing and basing humidity off of them for now, not hoping much on these damaged eggs. But I could put the bad air cells in another incubator if they have drastically different weight loss needs.

What’s the typical day range you will lose an embryo in a damaged air cell egg? Does it get more common to lose it as it ages or less?

I’ve read a few things that say if the embryo makes it to day 15, the air loss has essentially locked in the air cell. Is this true?

Thanks!!!!

I'm sorry I can't answer your last two questions because I have no experience with detached air cells.
However, I would think that any egg needs to lose the same amount of weight. For chicken eggs, that's about 0.65% per day. I don't think it would matter a lot what the condition of the air cell is.
A point on turning is that the first 7 days are the most critical time for frequent turning to produce healthy embryos. IMO turning is more important than concern about the air cells. If you don't turn the first 7 days, you are going to degrade hatchability regardless of air cell condition. Because really, the air cell location only matters as hatching nears anyway, does it not?

Thank!!. I have no idea when it matters.... I’ve never dealt with them before. :lau

They’ve been getting turned since I added them to the turners on day 3.

I’m going to keep basing my humidity off my six favorite eggs with good air cells and decide if these bad cells need special handling closer to hatch...

that's why I stopped coming for the longest time but if everybody just stays quiet nobody talks. So are you enjoying the shed you built a while back?

Just getting to where I can work out there again; only heat is the propane Mr. Buddy & only light is via extension cord, which was being used to power the heater in the greenhouse.

There was a tick next to the dog’s ear. As I was sleepily scratching him, I noticed it. It then fell onto my bed. Black tick, black comforter and sheets. This dog sleeps up against me. The tick was flushed, but now I am freaked out about ticks taking over the house. :oops:

I was asked to speak at a chicken festival later this month. Unfortunately, they want someone that currently has chickens that they can bring with them to show off and sell some. :hmm I don't think I've regretted selling my flock more than I do right now.

You obviously have friends with chickens that may be willing to loan you some to bring to the event. You could even go to a feed store, buy chicks and resell them at the festival. Try to do it. You'll be happy you did.
A class planner for our community college continuing education program contacted our 700 member backyard chicken meetup group looking for someone to teach classes. Considering my background in poultry and nutrition as well as a lifetime in adult education teaching everything from Soviet Military Liaison Mission to math, industrial automation and robotics, stone sculpture, gardening, Macaw care to drivers education and everything in between, I applied. I was hired immediately. What followed was almost 10 years in poultry classes for the 3 community colleges, the Humane Society, Gateway Greening, Missouri Botanical Garden, Midwest Heritage Poultry Conference and various other green venues as well as speaking at many of the area city council meetings regarding allowing keeping chickens.
