Of our four Myotonic does, I think Shirley has the most personality. In this video she is the one with the black heart on her chest. I think it looks like a bra. She woke up yesterday morning happy and dancing and fighting. I caught a bit of video. I think the funniest part is how their back legs lock up when they run down the hill. Happiness does that to a Myotonic goat.
Mary is a retired nurse with a passion for cooking and recipe development. Michael is a teacher with a passion for music and recipe taste testing. Together they are the Egg Farm. 
Your little goats look like they are having a blast!!!!
I have Boer goats and they think all day about breaking out of the pen.
Bwahahahaha, that does look like a bra!!
