A friend of ours leases chickens, pullets to be exact. He offered to lease us some, bringing over the coup and the whole nine yards. Basically they would clear the yard and fertilize it for us, we would take care of young chickens for him, and then he would take them back. There wouldn't be any eggs involved though, because they would be too young. I didn't see the point, because where is the fun in just having chickens to clear up your yard? I could borrow goats for that. It could be a mutually effective arrangement, though, if you want to focus on showing your older chickens, and you know someone who wants to spend less time mowing.
