We are relatively new to raising and keeping chickens and have some sex-linked chickens that are barred rock mixed with another kind of chicken. (My boyfriend’s cousin has been hatching eggs and we got chicks from him within a few days of hatching). So, out of 10, we knew pretty quick (within 6 weeks) that 4 were roosters and gave them away to others. Our “Roo” began developing fairly quick and he was the first that we absolutely knew was a rooster. He began developing waddles, a comb, etc by about 3-4 weeks. Keep in mind these were hatched around May 12th, which makes them about 9/10 weeks old.
We have another one that we are suspect may be a rooster, but hasn’t developed as quickly as “Roo” did. Roo began crowing about 2 weeks ago and crows every morning when he sees us come outside. Last week, I thought I heard another crow, but wasn’t absolutely sure. Yesterday, I heard another crow at the same time Roo was crowing, so I pretty much know there’s probably another rooster in the bunch. My question is, do roosters sometimes develop at different rates? I have added pictures of both Roo and “Polly” to see if y’all have any ideas. Thanks for your time.
