Our 13-month-old Buff Orp, Winnie, stopped laying about ten days ago. She seems perfectly healthy, alert, good appetite and everything. She doesn't have any mites. I've palpated her abdomen regularly and, in my inexperienced judgment, it feels normal. I don't see any signs of eggbinding or internal laying. Yesterday she was displaying laying behavior, and was going into the next box and digging around, although she never did lay. Today her vent looks redder than usual but everything else still seems normal. We think she may have laid an egg without a shell or membrane a few days ago, because there was what appeared to be some egg white on her butt fluff and some yolk on her nose. I am 99% sure she's not laying regular eggs and eating them. We have four other hens of the same age who are still laying as usual. They get layer crumbles, plenty of fresh water, scratch on cold mornings, veggie scraps, yoghurt, etc. Help! I don't care about the egg production, but I'm starting to become really concerned about Winnie's health. Is it possible for a hen to "take a break" from laying for a little while, and then resume normally? Could she be having trouble forming the shells (they get oyster shell but the last egg she laid was a little brittle)? Or could she have just... stopped being able to lay? There may be another part to this-- could they all be ready to molt? We got them last year in late February as day-olds, they began to lay in August/September and had a mini-molt, and they've been on 15-hour days all winter. Several weeks ago, Winnie suddenly lost a patch of feathers on her neck, and the other girls have been shedding a few more feathers than usual and looking a bit scraggly, although nothing extreme. Our black sex link has a tiny bare patch on her neck too. Winnie's feet and legs are also totally bleached. I understand the whens and hows of molting, but considering they've been on artificial light all winter, what if we dropped their light down to natural 12-hour day lengths right now? Would they enjoy a rejuvenating molt for a month or two and then begin to lay once the days are longer? The main question is, could Winnie's laying be related to this? Thank you for any help you can give!
