I wish ya'll would try the colorless iodine on these bumbles it really does work I gave the link a few posts back, I had a hen with bumble and when I read about the iodine I started using it on hers, I'd clean her foot really good with Oxine/water or soak it in Epsom salt then dry it real good apply the iodine[colorless] very important. Then use a qtip and spread the iodine all over her bumble top and bottom then do it again in 3 days it cleared up just doing this and I had been trying for months to clear it up using other things and yep I have the neo too.
