My 18 month old Araucana hen, Flossie, had finished her molt and started laying eggs again, only to stop a couple of weeks later. She hasn't laid any in over a week. My husband said he saw her in one of the nesting boxes yesterday and later when I checked there was a brown egg and a membrabe from a shell-less egg. I know the brown egg isn't Flossie's as she lays blue eggs. She seems perfectly fine; still eating, still pooping, still scratching. All the other chickens seem healthy and happy and the eggs have all had good shells, so I don't think it's a calcium deficiency. Is it normal for a chicken to stop laying for a while when not molting? Should I keep my eye out for any symptoms that might arise?
