If you want to farm worms for Miss Chook, I would suggest mealworms. They aren't slimey and the don't stink.. and the chickens will kill for them.
I recently started a mealworm box. All you do is put chick crumble in a plastic box, a few inches crumble will do. Put in a potato cut in half, or a banana peel and let the buggers go to town! Within a couple of weeks, you'll have your first "harvest".
The potato and banana peels are their water and the chick crumble is their bedding and food. Because there is not an abundance of moisture, it doesn't rot(rot=stink). And as long as you have a couple inches between the bedding and the top of the box, you won't have any escapees. The worms and beetles can't climb, and the beetles cannot fly..
I like growing mealworms even more than I thought I would. I plan on starting a few other boxes..
Mealworms have more protein than redworms too.
