Hi all I have four RIR hens that are a year old. We had such a smooth first year but recently things seem to be going downhill! About a month ago we had to euthanize one of our girls for a recurring impacted crop problem. Now we have a feather picker. They have plenty of room (7x12 coop, 12x12 run). I've tried upping protein, feeding hulled BOSS, Blue-Kote, Bitter Apple, slathering the other girls with Vicks Vapo-Rub... nothing seems to deter my picker! The others will peck back at her to sort of say "no" or move away, but it still is happening and one of my hens has a huge bald spot on her breast because of it. I'm very worried about what could happen if she winds up drawing blood. I've read on this board that sometimes removing a chicken from the flock and putting her back will help with feather picking. So, as a last resort I penned off a section of the coop with chicken wire frames, to make a sort of mini coop w/in a coop. My question is, how long should I keep her from socializing with the other hens? And has anyone else had any success with this method? I am desperate! I don't want to loose another hen. I'll be down to three.
