I bought a tractor/coop on craigslist and picked it up last week. It needs some retrofitting as it is really really heavy. It is 6 ft long, about 2.5 ft wide and about 3 ft high with an upstairs with the roost and nest boxes and a downstairs enclosed in wire. I didn't expect it to have a wire floor but with wheels on one end, it won't sit flat on the ground so that makes sense I guess. I plan on putting my bantams in there as the garden cart coop I made is just too small for bad weather. The wire on the bottom and sides of this coop is 2" x 1" Is that going to be a problem for banties? They will free-range w/in electric netting once acclimated to their new home. Also, the upstairs part is all wood. Should I change some of it to fiberglass panels to increase light? or will that make it too cold in winter weather? (I'm in SE PA) Here are some pics: http://www.flickr.com/gp/[email protected]/EJ9w92 I took off the sides to get a better look inside and to see what I need to do to make it lighter. I think I'll make one side of the top removable and maybe make an egg door on one end, removing most of the nest boxes and making just two in the end. But still not sure what to think about the wire on the bottom and how dark it might be upstairs. Does that matter?
