I bought two calves last Friday to put on my milk cow. One of them has had runny poop for a few days. On tue. I gave him half a scour pill. The next morning I gave him another half pill. Today I gave him a whole pill. He looks like he is getting dehydrated. His eyes are sinking in a little and when I pinch his neck skin it doesn't go back real quick. So I bought some electrolyte and pepto bismol. I got two tablespoons of pepto down him mixed with an egg and maybe a cup of electrolyte. When he pooed this evening it was his normal runny stuff but it was pink. It (the poo) is the consistency of thin clabbered yogurt. He gets up and walks around and nurses fine. Should I be worried about the runny poo?
