It's bad this winter but they have 6 sq ft per bird in the coop and over 14 in the run. They are cooped up a lot due to the cold and huge amounts of snow. I've tried everything but we did have to cull one 2 days ago. She was pecked so badly. ANyways, I have found that ALL of my Isa's are the culprits. The irony is that they are the younger birds. Is this a breed thing? Should I just get rid of the 3 Isa's that are pecking? I have tried lots of scratch, shoveling and adding hay to the run, EVERYTHING and they continue to peck. And it takes little to no time for them to induce some serious damage to the culprit. I also free range but they have no interesting in leaving the coop right now.
