I have a light outside my door and there are usually lots of small moths hanging out - so I just pluck a few (up to 10) and brush the dust off the wings so they can't fly and drop them into the brooder - OMG - chick-frenzy - they love them and run around chasing whoever has wings sticking out of their beaks - all gone in minutes - BIG treat, also I take some broccoli crowns and cut just the very tips off in tiny pieces (no stems) and they love it (for my older ones 10-14 days and up) and put a small dish of plain yogurt out too, although the first time they were afraid to try until I dropped a few bits of broccoli in - when they grabbed the borccoli they got some yogurt and found that "hey, that white stuff is pretty nummy too", now they will eat it as is.
