My RIR, Black Australorps, and Golden Comets are 19 weeks old and not ONE is laid an egg. I live in NC and its not that hot, but they have fresh water everyday and their habitat is clean and cool for them...WHATS WRONG?!?!
It's OK! pullets don't usually lay until 20-25 weeks. You are not alone(our hens started at that age. Granted, a lot of BYCers have been receiving eggs at 19 wks, but that's not the norm. Don't worry, your chickens are fine.
Nothing is wrong......No two chickens are alike in egg laying...commonly some lay at 19 weeks some sooner, some alot later...rule of thumb for all breeds 19 to as late as 6 months....sometimes diet plays into the rule....
