Its a good place to stash a bit of food until you are ready to eat it! I love it when they do this ... I have seen them walk around for hours with a piece of hay dangling in their face, then all of a sudden they wiggle their head, the tongue comes out and they are munching it. They look at you like, yeah, I knew it was there all along. Duh, there was a reason I put it there. I have also seen another goat come along and munch the hay out of another one's mohair.
Too funny Keren! Reminds me of the other day when I was pouring some grain into the feeders; Jenna decided she needed to get her head away and Libby comes over and wanted to eat the grain off her head, but Jenna kept running away from her. Never know about those rascals!
