I've got a batch in right now that were laid in an outdoor coop and it's ranged from 25-40 degrees, so I'll mark down what develops and what comes out. I seem to remember I did refrigerate some on purpose a couple years ago but didn't end up tallying males, might have been one of my bad hatches.
Please let me know what your count is.. that would be great to know.. If I didn't currently have a batch in my incubator ready to go on lockdown, I think I'd try it now.. if I try it after this batch hatches, I'm going to have to find homes for them as I do not have time available to babysit them after they hatch.. their just mutts kept for eggs, so I don't need to worry about selling them.
Ehhhh....my bet is that if this were true the hatcheries would have been doing it along ago.
Yes, we've hashed that out many times before. It's not economical to do on a large scale, especially when they get value back from male chicks as byproduct, but it's fun to play with on a small scale
Large scale would be needed to prove the theory, along with other variables weeded out(same parentage, feeding, environment, egg storage and prep, etc)...or meticulous management and records from a home hatcher.Yes, we've hashed that out many times before.

I can tell you the reverse is always true for me, if I run that incubator too hot I'll end up with more males than females every time.
I'm really not interested in hashing it out, lol. All I know is that there is an Australian study that was done citing which temperatures male embryos will die in greater numbers, and it seems to work that way for me. I'm not saying anyone has to try it.
