I'm not sure if this really a disease problem but it's not normal! The last couple of days I have found small pieces (marble size or smaller) of what looks like flesh amongst the poo of my hens. See attached photos. The hens do not seem ill. I wondered at first if it was some sort of foetus that had developed in the oviduct - it didn't seem like images I'd seen of lash eggs. When I cut them in half there seems to be a structure of concentric layers (3 or 4) like the layers of a onion. They did not smell strongly. Any ideas?
