Just wanted to get back with you. Got my hen to the vet and my vet highly recommended just putting ACV in their water everyday. She was going to put her on some anti-fungal med but never told me what it was. She really didn't seem that concerned like it was going to kill my chicken. I asked her about it spreading to my other girls and she just kept saying put 2 TBS of ACV per gallon of water every day. She also said as it gets warmer that they drink more water so their poop can be more watery and cause pasty butt. It wasn't going to be cheap fixing the broken leg so I said to the vet " I don't want to spend this money and have her die from vent gleet. She said she won't...it is curable. Sorry I didn't get any more info. I just thought I would let everyone know what she gave me but I didn't get that far. My girl wasn't fixable
