We have two bucklings born this year. One we are keeping as pack wether and one is going to a great new home. One was born 3/27 and the other 3/30. They are very big and healthy. The flys are getting very pesky, so I would like to castrate them as soon as they are ready. We are using a bander, and I have never castrated before. If I castrated them correctly now, what could go wrong??
