I bought 15 barred rocks from tractor supply out of a bin of straight run chicks. 2 weeks into this, I notice that one of my chicks has extremely thick legs, and a slightly larger body than ALL of the others that I have. Could this be an early sign of a Roo? Also, I have another chick who when I pick it up, it has a raspy chirp? It is smaller than the chick I mentioned above, smaller legs. The only way I know it is the same chick every time I get it is because it comes right to my hand every time, and its raspy chirp. I know nothing about combs, and it may be too early to even tell, but it seems to be turning an pinkish orange color before all the others.. 9 of the 15 are going to my boyfriend, and I plan on keeping 6, 5 hens and a rooster, I just don't know what age I'll know for sure what it is. I don't want to keep the chicks from him for too long.. Any good early sign detectors? I'm hoping to let him have his by the time they are a month old.. maybe a month and a half. Is this a possibility?
