looking sheepish

The English expression "looking sheepish" means to look embarrassed for having done something wrong or maybe foolish.   In other words, the way I look after trying to say something clever in French and then seeing the reaction on my French friends faces. But what did these guys do?

Sheep

I encountered these sheep on a recent bike ride near Amboise.  I've never seen any like this before.  They didn't seem to mind that I was taking their picture...in fact they almost seemed to be happy to pose for a family portrait.
