I always handle my chicks from day 1, that's how I have so many friendly roosters, only have 2 buttheads amongst my flocks, both in the same coop. One is just an ankle biter, not a concern, the other one hates my guts, but I still love him. Only reason he's around, is he's the only rooster of that specific breed, & he's beautiful. Will probably replace him, once I get a friendly one.
