I got tons of suggestions here when I asked about the potbelly issue and most said to put her on alfalfa. I had her on good quality coastal before, she gets fed through a nibblenet which slows down her intake and ensures that she gets the same amount everyday.
If she would have gotten pregnant it would have had to happen before she was 10 months old, she was with a herd of minis but I don't know if any stallions or colts were with her. When I got her she hadn't been wormed in at least 6 months, or seen a vet, was underweight with a skinny neck, you could feel her spine and ribs but she had a potbelly, that and the wintercoat made her look fat.
With a mare showing this kind of daily attitude how do you know when she's in heat?
I would love to just put her on coastal, I don't like having to deal with different types of hay and the price for alfalfa will go back up for the winter I'm sure.
Here are some pictures of her belly wise
Top left at 10 months when I got her, top right at 11 months, bottom two at 13 months. I need to take some updated belly pics
