As mobile chicken units go, this is a monster. It didn't start out that way, but it kind of grew with the impossible task of housing 24 chickens. The 24 will soon be split, and another mobile unit will have to be assembled. But, for now, there is plenty of room for the chickens to roost Our daughter had the brilliant idea for this unit, and the one thing we learned is that more is sometimes cumbersome. We can't pull this baby without our handy lawn tractor. We also learned that the wheels must go on the back of the unit, not several feet in or it doesn't pull at all.
