I have a flock of EEs (and a token Silkie hen) who have some loose stool every now and then. It kind of comes and goes, with normal in between. Nobody acts sick at all. They eat layer mash and whatever they find foraging for a few hours each day. They also get treats (lettuce, squash, bread, seeds, and/or fruit) once a day in the evening. Could it be that their systems just don't like the treats? I've read a lot about cocci on here, but have gotten the impression that it's usually in chicks, not adults. Any ideas?? Thanks!
