I have 2 pygmy wethers. Billie Joe is almost 2 years and bucky is about 9 months. They were both castrated by banding when a got them at 4 and 2 months. They constantly act like bucks, they get pushy, mount the does, make buck sounds, and even get possessive over the 2 does. What should I do? Is this normal? My does are both around 9 months old, one boer and one pygmy. The wethers are not bad goats, they can be really nice but Billie will also get aggressive with all of them by headbutting them especially around food. He was raised with mini horses so he kind of had to fight for his food so could that be the problem with him?
