I have three hens and a rooster, they all hatched and grew together they are 8 months. They are all friendly enough and like cuddles. My white head hen (Goujon) is quite calm and tolerates the black hen (Nugget) without too much bother. My second white hen (Cindy) is a bit crazy, she has accepted having a head hen but doesn’t like the black hen near them when in the garden, although the black hen works it and follows them around knowing what bed she can and can’t go into, the head hen is slowly starting to act up towards the black hen also on occasion. Cindy will keep black hen away from food and the coop during the day, they all settle back into coop fine in the night without issues. Today I put them in coop during day, Cindy wouldn’t stop attacking black hen, I removed Cindy to see how the three would get on, the head hen started chasing black hen around, she knocked the bowl which annoyed the rooster and he also grabbed the black hen which resulted in a lot of feather loss. I put them all out again and they are back to themselves again. What will I do with the black hen, she is so gentle she has never pecked any of them back and tries soo hard to be a part of the group, lightly pecking all the others and bowing down to them and I thought it was working until now. Any ideas…or is this normal? She is the nicest of them all and is even trying to make friends with the dog. Thanks in advance
