I went and looked at pygmy goats today. Want to get two. I found one female that I liked but not sure about another one. She has a twin brother that looks like her but not sure if I should get him. The woman said that males if not fixed are really stinky. and said that if I took him that she would have him fixed. Any input would be great. Also these goat are not registered. Should I spend the extra money and get a goat that is registered?
