I have a RIR hen that chases my Cornish X chicks (5wks), plucks the feathers from them and then eats the feathers. Is that weird or what! I always know it's happening because I can hear the chicks squawking and running away. They stay in a stall in the barn and the hen jumps in there to bully them and have a feather snack.
I have seven RIR hens and only one is pulling feathers. What does this mean?
