Just finished my tractor yesterday. Took some basic plans off YouTube and the internet and just ran with it. Frame is all cedar and the plywood is 1/2", painted with exterior house paint. Was a fun project and kinda added my own touches to it and tried to make it look nice as it will be in our backyard and we have to look at it. The chicken on the side has a 1/4"-20 threaded rod epoxied in it and I use it as a screw in handle to hold the side of the coop on securely. I got the chicken at the Dollar Store. Made it 2 ft. wide and 8 ft long so i could it through a standard door if I want to take them out front or sell it.
