I have read on here before that your fawns should take in 10 to 20% of their body weight of milk per day. My question is how accurate is that, and also can you feed them too much? My fawns were pulled at 30 hours and are now 6 days old. When I get finished feeding they act like they want more is it ok to give them as much as they want or should I limit them to a number of ounces per day? THANKS
