My chicken has favus. Last year, 2 of my 5 girls had it, but now only 1 does. It's pretty intense, so Ive been putting anti-fungi creme on everyone of my hens combs. I dont think its working, and recently the only hen with favus has lost weight and going to bed earlier than usual. Her nose is a small bit runny, but does any of this have anything to do with the favus fungi? If not, does she have worms? I have never wormed my girls before, they are all turning 2 soon. Any ideas?
