Yup... Sounds like she is bred........ Make sure and keep an eye on her and she should do fine..... I had a yearling stud colt that bred a couple of my mares one year.... Don't know if this applies but it did happen to me... Also bought a mare for her pedigree from a thief( I mean horse trader) and she was also bred.......... Was the ugliest colt I had ever seen.... I would guess maybe a shetland pony cross......... Butt ugly thing...... Had to drag the sucker around with my saddle horse to get it to lead......
