We had a calf born last week Tuesday - The calf would only nurse off 3 teats. The 4th one we cleaned out on Friday and the calf is now nursing on all 4. We did start Penicillin on the calf for 4 days. All seems to be well. The weird thing and we have not seen before is when the calf pee's the cow goes nuts and drinks it. She is still crazy about licking this calf consistently. Is this normal? She has free access to water at all times and hay.
