Currently the only horse you own that might be worth something is the WWE. Personally, I would geld all the other boys in your barn and release the mares. Then I'd save for some better rated stock- unless you're breeding for color.
Looking to bolster my barns a bit, so I am looking for SD World Class horses. I am only looking for LB stallions, with the exception of if you are okay with them getting gelded. Also looking for mares and geldings. Any breed is fine for now. PM is the fastest way to get ahold of me but feel free to post here as well.
