I will not be getting chicks until the middle of May so I have time to build a Chicken Tractor. I am not a carpenter but, I do have a neighbor who is and he is advising me. I want to move the chickens around with my llamas in hopes that the llamas will add some protection. I have all sorts of pedators here from fox, hawks, possums, raccoons and an occassional coyote. I research BYC everyday for hours on this subject. The problem is making it lightweight enough for me to move by myself on very steep hillsides but sturdy enough for winter. (Maybe I can't have both?) Here are my thoughts: 1.I want to build a modified Chick-N-Barn something I can also keep them in for the winter. I have viewed the ones on BYC including the modified Teacup Pterodactyl Townhouse (which I love). I will only have 3 to 4 standard chickens. 2.I was thinking to build the frame out of 2"x2"s and build the structure 4'x4' and approximately 40 inches high cutting the front and back from a sheet of plywood like the original, the additional 8 inches would be for the cupola. Put 1/4 inch Luan plywood on the inside, insulation in the middle and 1/4 inch Luan on the outside. I'll cover the outside piece with some pieces of levelor blind material. (plastic cutoffs from my blinds, I hated to waste them.Each one is 3 1/2" wide. Thought I could make it look like siding and protect the wood at the same time.) 3.The cupola would be vented like the original Chick-N-Barn, the sides would lift up (hinged) for cleaning and I would like to work out a system to use those sides to help vent as well. Maybe putting in a framed screen when the lids were up ( that would latch and I could take them in and out.) The lids would be on a chain that I could pull them up as far as I wanted to. (I listen to you Patandchickens) 4.I would like to add on a 24 inch wide nest box on the back that would also lift up. (divided into 2 nest boxes) Not sure about the dimensions here but I know I need 12x12x12 for each one. 5.Roofing material would be Ondura (got it cheap because it was damaged) 6. Roost might be hung on a chain so that it would remain level even if the tractor was on a hill. I'll talk about the wheel assembly and run in another post. What do ya'll think? Please give me suggestions or concerns because I don't want to waste materials once I get started.
