Meet my barn's surprise bundle of joy, Oliver! His mom was purchased last fall, and nobody realized she was pregnant until early April. (She's a maiden, and really didn't show much. It happens - ask Mary, who got 30 minutes to prepare for her mare to foal in college!)
He was then foaled the first week of May. We had about a month to prepare!
The people she was purchased from are not sure who the sire is, so I joked for a month that he was going to come out a blue eyed mule. He's actually a strapping bay colt that isn't badly put together, especially for an unplanned pregnancy.
My eye is so skewed toward baby ponies and not baby horses, I was amazed at how tall he is and how long his legs are! Hopefully he grows up tall and strong and becomes a good performance horse. It will be fun to watch.
