@gunndogs So we'll stop giving him medication, we're located in southern New Mexico, and as you probably know, vet is extremely expensive and don't have the money right now, as much as we want to take him, we just can't.
So what you're suggesting is that he has niacin deficiency? What exact foods would you recommend? He's been inside for the past week on a soft padding resting, we occasionally take him out to the pond so he can wash himself and maybe try to swim, but he immediately comes back to the shore. I just noticed that he was breathing hard, is his nostrils clogged? He is NOT getting better at all.
A niacin deficiency doesn't cause green poop. If he's still pooping green, and eating, he probably has a bacterial infection. @ethanj357
go get some crumbles for him and stop feeding him just corn.
