Some air sacs are good, some too small…help

[HuskerChickMom]

I am hatching bantam eggs for the first time. I’ve always hatched layers before so I’m not sure if it makes a difference. To me it looks like about half of the air sacs are developing regularly (slightly up the side of egg on day 15) and the other half are still just a circle at the bottom. Is there anything I can do? All chicks are alive and moving when I candled.

I keep humidity around 45-50% until lockdown, then 65-70%.

It's odd yours are varying size from egg to egg as they all should be relatively similar. If they're all viable, I guess I wouldn't worry. You don't have long to wait!

I’ve had the humidity at 50% the whole time. I thought it was weird to have some that looked good and some that were still a little small. They are different breeds so maybe that makes a difference. The smaller ones were mille fluer eggs and the other ones are salmon favorelle bantams. They are all spread out in the incubator so I don’t think it’s because of a cold spot or anything. Just a little worried because these will be my sons 4H chickens and he really wants a good hatch. Thank you for your reply!

Any update on these? I am
curious as I have some different air sac sizes as well. Thanks!

They all did great! All of them hatched and are healthy! Not sure what happened, but apparently it wasn’t as big of a deal as I thought.
