Is there a single word which means "not empty"? That is, a word which one might use to describe a field with one or more cows in it, as opposed to an "empty" field with none?
Full or even partially-full are not appropriate, because the number of animals is indeterminate, and the final count could be a single bull [which are best kept on their own] or fifty cows. Or three sheep. And the field is really only full when there is no more space available.
I'd prefer a single word, to go with the single word "Empty". Currently I'm using "has animals" which I feel is not particularly succinct.

I'm trying to figure out the names for different states of a set of items, empty or non-empty.
What I came up with so far:
HasItems seems awkward, I would rather use one word than two.
How do you call a set that is not empty, i.e. has at least one item, in a common language?
