I tried to get the vet to COME out, but they won't as they want to put the mares in stocks they said, for a safer exam. Both Jojo and Belle have foaled before, but the tobiano pony, Starling, has not (at least to my knowledge). I am treating all three as if they are pregnant for right now so all decisions regarding worming, etc. are filtering through that supposition. I am going to lease out Belle for the winter (the woman is picking her up at Thanksgiving), with the condition that if/when she foals, the leasee gets to keep the foal. The horses are on 8.5 acres, but we are in the temperate redwood rainforest, and pastures here have a LOT of clay and get wet, and stay wet in the winter. Keeping things at 2 horses should prevent the mud from getting bad. Thanks for the advice. If the whole pigeon fever thing dies down, or the vet can convince me the clinic is CLEAN, I'll take them in.
