We're bottlefeeding a fawn that is we guess around a week old, this one's an orphan. We're feeding him 4.5Oz, yet, he seems to still be hungry. Someone said that you shoudl feed 10% of the body weight, he weights 6lbs, that would be 9.6Oz though, seems a bit, much... I wanna clear that with you guys. Is that much ok to give?
