I was cleaning Buggsy's stall this morning and was just about to scoop up a pile, when "wait, that's no horse apple!". It was the tiniest bunny I have ever seen. He did not even have his eyes fully open yet. I have no idea how he got where he was, but we carefully put him back at the hole that gives access to where many animals are born and live: under the tackroom, which is across the isle from Buggs' stall.
While he sat on my hand he wiped off his nose and rubbed his eyes, and licked the salt off my fingers. What a little cutie!
