I have had as many as 23 but when my husband passed away we changed our direction from breeding to showing. Sold all of the broodmares, only had a stallion to show and had several geldings. We still show but do breed a mare a year with the hopes of a show baby. Right now I own 11, five of them live in homes as companions to either other horses or kids. I still own them but they have wonderful homes where they are taken care of and loved on. If they ever need to leave those homes, they come back to me. So that leaves me with 6 horses. One is a colt I bred and foaled out last year and will be showing this year, one is a 2 year old shetland stallion that I almost lost in 2009 but he is just awesome and will show this year. I have one breeding stallion that is a World and National Champion, 2 mares that are both Res World Champions (one is the dam of my show colt and bred for a foal next year) the other is due to foal anyday. The last mare is one I picked up last year that is just beautiful but with foaling issues, so she isn't here, she is in the care of my wonderful vet friend.
But while I only have four of my own here, I do have several mares in for breeding so I still feel like I have a herd LOL. But they will all go home.
