We have a number of Cuckoo Marans that are not laying. We knew they were a bit older when we got them, but could not get a clear idea of how old. They laid for a few days after getting them, and now nothing. Its been over two months now. They are recieving a much better ration then they ever have, plus lots of free ranging stuff. They are not molting at all, so I know that is not what is going on. They do look like they might be on the older side, but as most of you know, aging a full grown chicken is nearly impossible So, at this point, we are just waisting money on them. Would culling them be a good idea? Should we just do one, and check to see what her egg stores are looking like?
