Welcome to Backyard Chickens! We are glad you joined the flock! BYC is a helpful site providing all the information you need to know about poultry! There is always space for more members on the BYC roost! A cockerel's first crow will sound more like a cry because they are still practicing. Overbreeding usually depends on the rooster. I had a black copper maran rooster I used to keep with 2 hens and there wasn't one feather missing from their back. Hope you enjoy it here as much as we all do!
