Yesterday morning, my 9-month-old buck's underside was covered in blood. We gave him a bath to try and find any wounds, but there were none. We even checked on our other boy to see if he'd bled on him, but nothing there, either. A few minutes later, he managed to climb out of his pen to chase the girls. He was doing all the normal bucky things, but he was bleeding profusely from his penis. We put him into our milkstand, and within a minute or so there was a puddle of blood the size of a slice of bread. Everyone we spoke to said that it was probably from stones, but he didn't show any symptoms. We actually saw him peeing and spraying himself. He didn't even seem to be in any pain at all. After that, he stopped bleeding, and we thought he'd be okay. We checked on him at 5:30 AM, and he wasn't bloody, he was chewing his cud, and walking around, and generally being a normal, healthy goat. We were so relieved that he was not bloody, but by 7:30, he started up again. He and the other boy broke out AGAIN (I really don't know how they do it!), and chased the girls all over the yard. He's having erections, peeing, tongue flapping, all the obnoxious buck behaviors. He is currently locked up in his house. Has anyone seen this type of thing before? Thanks in advance for any guidance.
