My flock of twelve hens are picking each other horribly for sometime now, started off post molt, then I mistakenly thought mite issue, so the behavior escalated all that time. Added cat food and black oil sunflower seeds to their diet. I've tried separating first just the most assaulted, then the most aggressive with NO positive results! Is there ANYTHING that can be done at this point?? Will they eventually be cannibalistic? Should I just be culling them all? Ugh….any ideas surely appreciated!
