We bread one of our alpacas 7 days ago. Today we tested her. She went down right away but then she screamed! Not snorting or anything like that. She screamed a really shrill scream. I took her out because to the novice ear this sounded rather painful (I could be totally wrong but it was just hard to listen to). I thought maybe she is already pregnant but cushed because she is just very submissive. Is this screaming normal? What does it mean? Should I worry or not interfer? Maybe it's time for an ultrasound?
