Well, my daughter and I left for an 8 day trip to the NBHA youth world barrel race and since we didn't want to make my hubby work too hard we put the mares and my stallion out in our mini pasture. That just left him with the moms and babies. When we returned, my mares are huge! Two of them were mares that I had bought underweight and was working on filling out. Well, they are filled out now, but not where I want them. Never knew they could blow up so fast. Little blow flies. No founder though. Thank the lord. How do you guys who leave them out 24/7 cope with them getting so out of shape? I am planning on selling some mares and now I doubt anyone would want the heifers.
