Hahaha, ok, so firstly I would like to say that I have noticed the same thing as chickincrazy, in that my chooks will eat worms they find on their own. Maybe the ones I can catch are the slow, gross kind
Secondly, cheers to crunchy grasshoppers!
My chickens, like most, are constantly on bug patrol, and really love just about any creepy crawly they can get their beaks on. However, they aren't very keen on worms. I find earthworms and bring them to them, and a couple might pick at them, but most just turn up their beaks and walk away...
