I just added a new 6-month-old RIR rooster, and he has never been handled by his former owner. I want to tame him, to be easier to catch, and to sit in my lap, but he is hard to catch. When i manage to catch him, i hold him for a few minutes, then let him go, but the whole time he is in my arms he shakes. But he never pecks of struggles. He won't come near me and doesn't eat seed. I really would appreciate any advice. Thank you!
