Guys, thanks for all the treat suggestions! We are excited to try all the (non-bug) ideas. Ok, so someone mentioned grit. If your chickens have all-day access to a dirt run, do they still need grit? That's something I'm not clear on. Obviously, there's pebbles and gritty stuff in there. Would they need additional grit (store-bought or whatever) when I give them treats? I'm assuming they're eating bugs in there already and we haven't had any problems. Thanks again for the help!
