My new 8 month old Brahma hen is being bullied at night by the head master ( almost 3 years old EE hen) the two older hens were separated in another cage in the run with everyone ( I also have 2 Ayam Cemani about 7 months old) but I noticed the two older hens would not sleep in the attached hutch they would sleep outside in the cage, it was starting to get in the teens at night so after several days I let them free. I wanted to keep them in for at least a week or two. Now the older hens are pecking at the Brahma but not too bad that I get concerned, they used to be more nasty before I caged them. But now at night I see the older hens make sure the Ayam Cemanis sleep near the egg nests ( there are some roosts in there) and won’t allow the Brahma to sleep on the roost with them. I put her in there with them and the one starts pecking her when I start to leave. When I stay there she almost behaves. Will those chicken “ peepers” work?
