got 3 baby geese last week. went to check on them tonight. the smallest one is very limp when i picked him up noticed he has a whitish diarrhea. he's having difficulty breathing and has a hard time standing on his own. gave some electrolytes and put him under a small heat lamp. any other suggestions? he's been eating well and has been grazing on grass some. i noticed yesterday he had a little diarrhea but he still had his energy. pretty bad shape now. any help appreciated.
