good evening to everyone. I have a calf that was born in March and was doing well. He is on grain and hay. Eating great and gaining weight good. I started kicking him out at night onto a new grass exercise lot at night and things were good for about a day or two, Ever since then he has had diarrhea I thought I had it cleared up but it just started again. No other calves have it? He is not losing weight and he is eating hay maybe off grain a little bit but still eating it. Might act a little sluggish but not to bad. what could cause this or what should I be looking for?
Thanks in advance
