I'm a new flock owner and they're coming up on 16 months this week. My rooster's tail feathers are falling out and I've noticed his hackles are starting to get a bit thin. My female EE's wings are starting to thin out too. The other birds (GLW and Legbars) don't seem to be losing feathers at this point. I've read that molting typically starts at the hackles then basically works its way down. Is that just the typical pattern molting takes or could it be something else like parasites? This may be a silly question but I'm wondering for myself and any new owners who don't know what to expect.
