A pleasant surprise! My jaw would've dropped to the floor if that happened to me.
The breeder said she was surprised herself with Callie because one day her dam was missing somewhere in her many-acres field and the next, the dam was coming out from behind the trees and back creek with a foal at her side :)
foals are sooo stinkin' cute. When I was a kid, the barn I went to had a yearly breeding program. Paint/QH foals that I wanted so bad but instead I got the 20 year old gelding that no one wanted :P Finally got a foal when I was in college.
