I just put my chickens on their roost for tonight. It's only their fifth day going out so I have to help them, thus by picking them up and putting them on the ramp. Unfortunately I have had consistent problems with one particular Silkie roo pecking me. It's been from me picking up their feed holder and he pecks to me petting or picking up another chicken and he REACHES across their body to peck me. I have three other Roos and they've all done this to me also. Yet whenever they do this I clamp their beak shut and tap them on the head. All be other ones stopped pecking after a time or two of putting them back in their place. I really love all of my chickens and he's only 8 weeks old and I don't think he's a bad chicken I just don't get what his problem is. Please help. I don't want to kill him or rehome him.
