With the exception of molting and broodiness, my Icelandic hens were laying like clockwork. I was growing out the new roo, he was right by the hens so they were as used to him as they could be without them actually being with him. Anyway, since he has been with them, they have only laid three eggs. I think its probably stress and will even out in time? They get good food and treats, fresh water etc. so I know that isnt the problem. Neither are there too many-crowding.They are around a year old. I have read that its normal for flock egg production to ebb and flow and that makes sense to me.
