Feather growing speed

[Barredrocks24]

I have four barred rock chicks and one is growing feathers far faster than the other three. Should I be worried that the other three might be roo's?

Honestly, it's really difficult to sex them by feather growth. I'd just wait to see what they turn out to be. Small differences in age can make a big difference, and some breeds feather different than others.

Welcome! Differences in feather growth rates only predict sex if the birds are bred for that trait; otherwise it's random. Mary
