Good for you for having sense enough to know they do not eat metal. I don't know how many times I have heard people say they eat cans. Head shake! But they are fun. The kids are terribly funny to watch. Also, goats do like attention, affection too. One story for you.
We had made a big bowl of spaghetti for dinner and had it on the kitchen table. For some reason or another everyone was in another room. No one was in the kitchen. I heard our back door slam and went to see who came in (we had family in a couple of houses across the street). Well there stood one of our biggest does at the table eating our dinner. I do not remember what we had for dinner that evening but it was NOT spaghetti!
