This is our first year breeding. We have kept our buck with the two females that we want to breed. We know he mounted one of them but don’t know about the other one. Both have put on a bit of weight but other than that we can’t tell if they are pregnant. We don’t know if they are just fat or pregnant. We are not going to pay for ultrasounds on them. I’ve palpated their bellies and listened for a heartbeat. Still can’t tell. Any advise?
