I don't know how else to put this, we have a heifer calf, lost her mama, so weaned her early, she is a little over 2 months old. She was on grain and eating a little grass, so is OK there. We went ahead and put her in with the rest of the weaning calves, they are several months older than her, but she eats great, both hay and creep feed, drinks water, poops good, good firm poops, but she carries her tail out and stands hunkered over like she is trying to pee. We watched her tonight and she did pee, but not sure if maybe she has some kind of infection or trouble back there. She got a shot of nuflor just for good measure. Any advice?
