A Cornish Cross (Breeding?) Journey

[Morrigan]

I hope the hatch goes well for you. Broody hens are the best. Very curious to see what you get.

Day 10-12 now and there are two nice looking Chunky eggs and the OE egg in which I cannot see through. Cracked open the 5 duds and sure enough zero development and the one was indeed a double yolk. These duds looked like scrambled eggs which I found odd. I’ve incubated infertile eggs for the whole 21 days and they were still intact with only a more watery egg white and flatter yolk. I assume it is a result of a less sterile environment.

Lots of causes
I have it from stress I believe... whenever there's raccoon prints on the coop, along with stopping laying for a week.

In the spring I was hatching at a 95% success rate with most eggs being fertile.
Ever since it turned hot, about half of the chicken eggs have been fertile, but nearly all of my quail eggs are fertile?

It could be the heat but I think in my case it has a lot to do with her and the cockerel being so young. Poor Chunky will pant even in mild 75F weather. We’ve been getting in the low 90s with humidity so she’s getting a bit stressed. Luckily the temps will be in the 70s next week.

The SLW X BJG cockerel sprained his leg or something so he’s been gimping around for a few days. Looks like he’s putting more weight on it today so must not be too serious. Really slowed him down though and I’m sure the pullets are fine with that.
