"Boys will be boys" haha. Sometimes the friendliest chicks grow up to be the meanest roosters. I don't think you can change it. Personally, I never keep a mean rooster no matter how I felt about him when he was little. If he's hurting you now at just 3 months or so.....it'll get worse when his hormones really kick in.So I have my two little handsome cocks Almanzo and Royal I think their around 13 weeks I can check so far I’ve had a great relationship with them they like to sit in my shoulders come when called follow me come to me when they see me yesterday Almanzo my top cock couldn’t get into his run I had just put them away with treats and he really wanted them I went to pick him up like I’ve done all the time he trapped my hand and wouldn’t let go I gave him some time to back down but he didn’t so I gave him a smack on the back so he would let go i didn’t do it hard but he was kinda hurting me he left a big mark I felt very bad right after what am I doing wrong? He was fine with me this morning but I just feel horrible
