Suddenly this last week I have been getting no eggs except from my one renegade hen who refuses to laying in the nest box. The nest boxes are completely bare.(they are filled with the usual shavings) I have 6 hens, 4 who are laying and suddenly no eggs. The two non-layers are 26 and 23 weeks. Is is possible I have an egg eater? Can they do it without leaving a trace? I've checked my nest boxes for a bit of egg. I have read old threads on this: They have plenty of free access food. They free range part of the day. They have oyster shell. Three boxes for 6 hens. I check for eggs three or 4 times a day. Fall is arriving early here, and we have had sub-freezing nights more than once already. I don't consider that a big deal as they winter in our coop without additional heat or light in the past; they slow down but never just stop. Is it possible that the sudden arrival of this weather has caused them to divert energy to heat rather than eggs and once they adjust life will be just fine? Any thoughts on what is going on here and how to address it would be helpful .
