Yeah, but I've got no place to put her except with the boys, and Bob, her brother, is a young stallion, so that wouldn't work either. Bluebell's as fat as mud, so I'm not worried about her getting "pulled down". Other than that, I don't know of anything that it hurts by leaving them together, so she'll just have to wean her herself I guess.
