I guess I did the wrong thing with my cockerel because I handle him a LOT. LOL He was my first successful hatch. He's almost 10 months old now & the only one he's aggressive towards is his father. He stays as far away from every human except me & he lets me handle him so much he's pretty much my go-to model:
I think a lot of advice here is to not do everything I did, so he might literally bite me in the butt later on (like his father did over the weekend while I was bent over in their pen). I treat them all the same, the males & females & it's been working for me so far. I'm sure others have better advice than I do!
