Hello, I have a sick chicken who is basically just standing still in my yard most of the day puffed up. Her comb and face have turned really pale and she isn't eating or drinking much but will if you put it in front of her for a little.ive checked her for mites/lice I don't see anything and I checked her poop I don't see any worms? She has no discharge from her eyes or anything and her breathing seems fine. She's been this way for about a week. All my other chickens are doing fine? I've put electrolytes in their water to see if that would help but doesn't seem to be working. Any help would be appreciated, I am very new and don't know much about chicken ailments. Thank you for reading
