I have a 6 month old bantam who has been molting, lethargic for about 2 weeks. She was just standing in the run with her head tucked under. Other birds pecking her ( she used to be number 2 hen). She is extremely light now and losing her balance. Brought her in last night-Gosh her poop stinks!! First it was runny clear and VERY smelly- now it is just mustard yellow watery. Started her on Solumet last night. She is just listless and pushes her food around. HELP! What is this worms? Cocci? ???
