Hi all- I have a problem with my hens. Lots of feather picking, feather loss, bruising and some small wounds. I assumed they were doing this to each other. Mostly butts, around tail feathers and a few heads. Figured winter boredom, pecking order issues,etc. I've been using Blu-kote and peck no more. Added enrichment where I could......a new perch higher than the others, extra feeders, flock blocks, cabbages, toys, etc. I can't seem to figure out a culprit or culprits. Now I'm wondering if they are doing it to themselves?.......I see them do it sometimes. But sometimes I see them peck at each other. How do I know? I don't see any bugs......but I'm getting to the age of needing readers, so maybe I'm missing it? I've only had chickens a couple years so I'm still kinda new at this. Advice please!!
