Have any of you ever had a boer goat- or any goat- go too long? We have been raising boer goats for just 2 yrs. now and before the breeding was done at our place and I knew the due date. This one we bought pregnant. She is huge, has bagged up a bit and looks plain miserable. I thought she was farther along, but maybe not, now I am worried. What had been your experience?
