There are several ways to tell, but the best is to have a vet check her/it out. He/she will be able to see if there is another problem or if she is in fact a freemartin. If she wasn't born twin to a bull the chances are still she is one, if she was born twin to a bull the chances are great that she is. Have you ever observed her in heat? Has she run with a bull after she was old enough to have started cycling?
