I just added (2)1 year old hens to my small flock of 2 EE's, 2 RIR's and a Black Roo. My Roo is beating the crap out of the 2 new hens every time they get down, they are trying to hide in nest boxes and in corners. They are even sleeping in the next box( I go out and move them to the roost every nite). He tries to pull them out of the boxes, he jumps on them and pecks their head and pulls their feathers. He's not trying to mount them, I think he just don't like them. This has been going on for 4 days and nites. I moved him to a separate pen earlier today and when I went out to check on them the 2 new hens were on the roost with the other 4 hens. Do I let him back in with them in a few days? He has always been a gentleman with the other hens, but he is bullying these 2 non stop. Please help me out! My coop and run is a 20' x 20' open air coop and run(3 sides boxed in) so space is not an issue. The roo and hens can see each other but are separated by a wire fence, thanks for any help you can give.
