I’m pretty sure my chickens have started their first molt. They’re about 18 months and there are a ton of feathers laying in the coop. My one hen has fully finished it and her feathers have all grown back. I’m concerned about my roo because he now only has one tail feather left. Is it normal for them all to fall out? My other roo still has a few although not as many as usual. The one just looks so strange with one tail feather! Here’s a picture from a couple of days ago when he still had a couple feathers left.
