OMG she is DARLING! I have been coaching myself for years "I do NOT need a mini donkey, I do NOT need a mini donkey" because I know they'd be potato chips for me. I love her, she's a dollbaby. Can't wait to see the new pictures of her! I know mini-horses are a different world than full size to foal out - you MUST be there when they deliver, and more often have to be involved. I would recommend calling around to the mini horse breeders in your area and see if you could get someone willing to be on call as a midwife if needed - they would probably be better in the circumstances than an inexperienced vet.
Please keep us posted, absolutely enraptured to see a mini hinny/mini-donk baby!
