I have done a search for this already. My hen has a stubborn bumble foot. We have been soaking and wrapping, cutting out bumbles and soaking and wrapping some more. Every time we wrap it we put tons of neosporin on it. There was some improvement, but it seems to be relapsing. I 've been able to find any of that Koi fish medicine locally so I bought some Penicillin G procaine (injectable with 300,000 units of procaine penicillin per mL). My search has shown me that it is normally injected into the breast, however, one poster said that the dose could be increased and injected under the skin on the back of the neck. Is that OK? I would really rather inject it under the skin, rather than into the muscle. I know it sounds stupid, but thought of injecting it into the breast really puts me off. I can remove the plug from the bottom of her foot and squeeze junk out. I can cut the huge swollen knot on the top of her foot with a razor blade and remove hardened pussy masses. I can vaccinate my own chicks. I can vaccinate my horses. Heck, I've given myself shots. But I can't stand the thought of sticking that needle into Cher's chest!
If the pen-g doesn't work, I will order the fish medicine online.
