A have a hen who is continually picking and eating the neck feathers of the other chickens. I’ve increased protein a lot, they have plenty of space in the run, they free roam for hours each day, they have lots of distractions in the run, I even tried spraying butter apple spray on the girls necks to see if it would stop it. Nothing has helped. I’m thinking I need to try peepers? But if peepers stop them from seeing directly ahead, won’t they struggle to find bugs and such when they are out foraging? I’m at a loss.
