So, I built a new duck tractor last week, that I'm using as a grow-out pen for Pekins and chicks. Basically, I cut a cattle panel into 2 7 1/2 ft pieces, built a frame 4 ft wide and about 8' long, bent the cattle panels into a hoop, lined with hardware cloth, and put a tarp over all. It pulls fairly easily.

My idea is to build a bottom that I can sit the tractor on ,and use it (them, I'm building another) as breeding pens in the winter/spring for my BEI. I have enough room in the poultry house for two of these, and then would use them again in the Spring as tractors. Right now I have two usable pens inside. This, therefore, would double my pen space..

On another note, I'm trying to hatch some Buff American Goose eggs right now. I don't have my poultry fencing up at the farm yet, so what you think about putting a breeding pair in a tractor, to minimize aggression? I have a tractor that I built several years ago, using two 16' cattle panels for the sides and top. It measures about 8'x9'. I have to use a mower to move it. It's lined with welded wire, which adds to the weight quite a bit. I would keep the geese with the sheep in the winter, as I don't want them hurting the chickens.
