I am helping a friend with a calf which is about 3-4 months old. He has been laying down, is small compared to the other calves and is very weak. We're not sure if he is nursing or not or if the mother is producing milk. He goes over to her but doesn't actually nurse. He won't take a bottle, he doesn't have the ability to suck so we poured some of the drink and he swallowed it fine. He is urinating so we know he is getting something. I am 2 days into the "cattle" business and any help would be appreciated. My friend said he was going to see if he would eat some pellets tonight and give him some more of the drink.
