We have a training farm and currently have around 15 lol, give or a take a few because the amount changes weekly.
Also should have added in my actual expense that we own our hay fields & equipment for baling, so the cost of "hay" in my calculations is field maintenance & fuel for the tractor & truck to haul wagons. Didn't add wages for hay help. Also didn't add the thousands I spent on "extra" vet care, this past fall Woodstock had a tendon injury, cold laser therapy, ultrasounds, xrays, etc, etc, etc. I've got close to 5k in his treatment alone.
