I have a 2 month old poult who doesn't seem to be doing to well. It doesn't walk and just likes to sleep. It does eat and drink if you stand it up to its feeders. I have one other poult i bought with this one and he is doing amazing. Its poop is normal looking, i don't see any swelling or sores of any kind. I have had it in the bath tub for 2 days and it doesn't seem to be improving at all. Is there any kind of medicine I can give it? or should i just let nature run its course?
