Meat bird tractor, using mostly salvaged materials, built in a day. Size is 10X4X2. There is a door/lid on each end, and hardware cloth predator guard to keep the critters out. I still need to add latches, and a handle for moving it. The wheel assembly is from a kids' tricycle wagon. Frame is made up of 2x2's (ripped to width from wider dimensional lumber). Birds in the pictures are layers on their first foray out of the brooder.
