This spring I plan on building a chicken tractor coop for some meat birds. What would be a good bird that won't get too many flip over deaths and is relatively large. Don't mind how long it takes for them to mature as long as they can be butchered within a few months. Some coop plans or pics would be much appreciated. I want to do a square or rectangular predominantly rabbit wire (1/4" heavy guage wire) coop and I plan on raising about 100 birds. Thanks- Will
