Well I have been breeding my goats for many years. But finally got my own buck! And at 7 m of age he bred his first doe! She was in with him for the entire day and at least 3 times I saw him thrust, throw back his head, and fall backwards off the doe. LOL! So I have my dates marked to check for heat in 18-21 days. But it looks like he was able to ensure she was impregnated!
