Whoops, hit post too early.Thanks for the timely reply. So you don't think it's worms or some sort of parasite? Does such a product/treatment (Corid) impact their eggs at all? They've been raised on organic everything and filtered water their entire lives since I got them so I normally try to avoid anything chemical, pharmaceutical or potentially negative for the quality of eggs. Is there a homeopathic version for either cocci or de-worming? Thanks again!
To answer your question on the worms, if there's nothing visible, it might be worth asking the local vet to do a fecal float. Then you can at least know what you're dealing with and how to best treat.
