We have a surplus of slugs, especially with all the rain this summer, and I haven't seen a chicken give one a second glance yet. That's the one thing I wish they would consume and so far have seen no evidence of it. Why is that?
I have one that will eat them from time to time. Along with those nasty shield bugs (stink bugs) we have here in SC. She will eat pretty much any bug, it is really funny to see her pluck a wasp right out of the air and gulp it down!
