I cant add much to the link provided for sprouts. Thanks Baron. Here're my thoughts:
You can sprout in anything and I've done it in all sorts of containers for my own consumption. Don't use metal containers for sprouting, though. Plastic or glass will be fine.
Be mindful to adjust the quantities depending on the number of birds and, of course, the size of your sprouting containers.
Dont sprout more than the birds can eat in a day or two. Two day old sprouts are about as far as you want to go. After that, the sprout gets "leggy" and will begin feeding on it's own store of food energy - which defeats the whole point of sprouting for chickens. Freshness is key.
Ideally, you'll want to keep a rotating stock of sprouts going, to ensure a constant supply - so put in a double supply of sprouting containers, FIRST!
I would go to the thrift store or Dollar Store and find some cheap 2-3 gallon plastic containers with lids. That's really all it takes.
Give it a test run and work with it for a week or so and you should have it down pat.
