I recently acquired two 1 yr old hens to add to my flock of 5. I have them quarantined in a separate shed for safety. The rooster knows they're there, he's looked at them through a window and can obviously hear them. The flock free ranges every afternoon and puts themselves to roost by 7:15 then I go lock them in for the night. But last night the rooster waited outside for me and attacked me!!! He seemed very angry. I proceeded to display my dominance and pinned him on the ground and held him there for a few minutes to send a message. Tonight he didn't attack but I could tell he was upset! Do you think this will continue or should he return to normal behavior once the new hens are added? I really enjoy having him and hate to have to get rid of him. Advice please! Thanks.
