I personally don't feel that requiring the mare to carry her own foal is a bad thing - it ensures that the mare is properly cared for throughout her pregnancy and when the foal hits the ground. How many of the average broodmares out there would be shifted to the back the property and barely looked at if they weren't going to carry their own foal? Mares receive good feed, vitamins and proper vet care - do we all think this would continue otherwise?
I think from the general public's view, they want to see this mare's foals. Heck, I get excited when we get in a foal by/out of somebody important as I'm eager to see what the foal turns out to be like.. this year we've got an alphabet soup grandbaby, and it's my pick of the bunch just because I was a fan of alphabet soup (I'm dreamin of group 1 glory here guys haha!)
I'm delighted she has improved, and I'm sure that every possible step is being taken to achieve a full recovery.
Stop for a minute, open your mind, learn. You may not agree with what I say, I may not agree with what you say but we will both learn something new.
