Wow - overcrowding. Never thought of that. I've got 7 birds in a 10x8 ft enclosure, but I was thinking about upsizing anyway. Thanks for the advice. I think, I'll open up the run and see what happens.
Had Chickens 5 or 6 years now. We have brown leghorns & Isa Browns this time round. We did have a Rooster not too long ago, but he was better suited for pot pie than in the yard. Our girls have bald or bare spots on their backs, exactly where their feathers begin to fold upward for the tail...
