I usually separate my blind mille fleur hen from the flock but today I wanted to see if the other hens would tolerate the blind one. One bantam cochin hen did a sideways shuffle towards the mille and jumped on her for an attack. It was rooster behavior. I believe if I didn't take her off the mille she would have killed her. The cochin isn't an aggressive hen usually. Has anyone else experienced this kind of behavior towards a weak hen? I'm not sure what to do and any thoughts would be helpful.
