Ever since I put my Silkie, Harry, in with some other Silkies he's been sick
. When he first became sick I noticed he and the other chickens had mites so I thought maybe that was why he had become so skinny, mopey, and with runny poo. I dusted the chickens and getting rid of the mites was a success but Harry didn't seem to get back to his old self. So, I began putting grower/starter in their feeder and giving them plain yogurt every other day and I also gave them Gatorade in their waterer. I think the Gatorade might have helped some but I haven't tried it again. I also put Wazine wormer in their waterer sometime after the Gatorade and that didn't help either. Even with Harry eating the grower/starter he still hasn't gained any weight. He also shakes his head like he has mites but when I check him he doesn't have any.
I have tried everything I can think of to help him and nothing seems to help. I would appreciate any advice I can get
. Does anyone have any ideas?
