I have a small flock of 8 hens (all 8 months old) and up until about a month or two ago i don't think they really had any sort of pecking order established but they do now and my poor partridge Cochin is on the bottom. She's so nervous to eat around the other hens and runs away when they approach. She even runs away from treats if my Hamburg approaches even though she's a third the size. Is there any way of helping my poor girl out? She's so nervous around the other birds now and she wasn't like this, she won't even forage with the group anymore.
