I have a 6 day old angus calf that I have been having trouble getting to nurse. The cow and calf are penned together now but still not nursing. The cow has a plenty of milk but the calf acts like he doesn't want to nurse or even try. We have been feeding him twice a day with milk replacer. Had no trouble getting him to suck or finish the bottle. However, this morning his left eye was watering and by this afternoon had turned a blueish/white color and he also seemed to have lost his balance. When he was walking around he would just waver back and forth like he's drunk. Any thoughts as to what might be wrong?
