It's a bit late now but....
I don't think goats should be mated until they're 18 months, so they kid around their second birthday.
Until then they're not fully grown themselves.
I lost one, very dear, goat to pregnancy toxaemia when I took the advice of an experienced goat-keeper and mated her as a kid. I was devastated and wished I had not listened and stuck to my own feelings about it. I now find the woman is in a minority of one on this view in our goat society but very vociferous about it - I am furious she peddles her mad view to newbies and think she contributed to Daisy dying.
If, as Anke says, the pregnancy can be terminated, I'd do that.
