I have had them for three weeks, the RIR has not layed an egg since I got her, the leghorn layed every other day pretty well for the first week, the ee's layed every few days, and I am not sure but I think the cuckoo marans hen was laying every few days as well. Now none are laying, except maybe the cuckoo marans. They are all between 1 and 3 years old. They were supposedly laying well before I got them. My other girls are laying every day almost. What is their deal, do you think?
