Hello, will a calf scour when his mother is bulling, same as foals do at 4 weeks. I had nearly all my calves scour with crypto and all got better, this one is the oldest 2 month old, he never had crypto scour but now he's been scouring green/brown the last few days he's lively and sucking normally, he's on hay as they are still in .His mother is bulling yesterday and today
