Does anyone have any experience with Mycoplasma meleagridis? It is a primarily a turkey disease but can be transmitted to chickens. It is egg and/or sexually transmitted. This may be what is going on with my Isbars. It is incurable but you can treat the eggs and keep it from transferring to the offspring. The problem is I can't find the product, Gentadip, anywhere, it seems to be discontinued. I have a phone message placed with OSU animal diagnostics lab maybe they can give me more ideas of what to test for. The other other thing I have found that may answer the problem is that it could be some form of e. coli.
