You remind me of me when I first started a decade ago. OMG, my chickens were so spoiled it was ridiculous! They still are, of course, but not like then (course we've put on some years ourselves). Have also found raisins are their all time favorite, used to use them to train them to come in at night. When they saw those, they came a runnin'!!! Kinda expensive, but they're not particular about brand names, get the cheapest out there as long as they're not treated with preservatives. They will climb all over you for raisins.
) I won't take the chance with something purposefully given. It's just too easy to boil or bake something. Even a glob of hamburger meat. Just pretend it's a meat loaf or something. Put it on a cookie sheet or in a loaf pan and bake away.
