I have a doe and I'm not sure how old she is, but I'd guess around eight or nine. Her last kidding she had a single doeling, and she carried her very well, no problems or anything. The year before that, she had twin doelings, and she kept prolapsing. Not a HUGE prolapse, but enough to make me wonder if everything was OK. It turned out fine, but the pregnancies before that (she's always had multiples except for this year) I remember her prolapsing at least once. She's getting older and she had issues with her eyes this summer, but it got better. I've noticed her walking different then she used to and I was just wondering what everyone's opinion on when to stop breeding is.
