Hi Kim ! Just curious, I havent had this problem YET but would diflucan be safe for a chicken ? Its the pill women take for yeast.Lotrimin (clotrimazole) or Monistat 7 (miconazole) are usually good applied with gloves once a day. If that has not helped or it has spread, it may not be a fungal infection. A vet can do a skin scraping and look for the fungus. Pictures can help identify certain problems.
