One of my 6-yr old black australorps had a good molt back at the end of August. By October she was back to squatting for me and laying a few eggs a week (her usual). Now, in late Nov. she is blowing off feathers like a pillow fight. Every time she shakes, she dumps feathers, which seem to come from underneath the more external feathers. No large wing feathers or neck (cape?) feathers have come out this time around. Yet. She has stopped squatting and laying. I'm 99.999% certain this is not external parasites, too. I'm not seeing creepy crawlies and coops were cleaned out this month; coops plus girls were treated with Elector PSP. My other 5 girls seem to have completed their molts at this point, but who knows who will kick in another session! Is it typical for molts to be multi-stage like this, with egg-laying resuming in between 'sessions'? Anyone had similar experience with their girls? How old were yours when this happened?
