That's a very useful and informative link, Chris, thanks for that. Obviously fowl pox is another of those nasties we all have to be alert at looking out for. I notice the article recommends consulting a vet for diagnosis and treatment, which was exactly the point I was trying to express. Of course force-feeding is not outragious if a vet considers it necessary and has shown you how to do it, but I don't think we should be encouraging people to try this on undiagnosed birds that we haven't seen ourselves and which haven't been seen by a vet, any more than we should condone people giving antibiotics or other strong medications to birds unless vitally necessary and properly prescribed. Fowl Pox is an infectious disease which can spread throughout the flock and the spores can last a long time, so personally, if it was ever diagnosed in one of my birds, I would have no hesitation in culling immediately rather than attempting treatment, in the interests of the rest of the flock as well as future birds I might keep.
