I happen to own a little four foot by four foot chicken tractor, that is very secure. I just built it to have somewhere to put extra chickens in that I need to separate from the laying flock, which is turns out I really never need to do. Anyway, I was wondering what the mot Cornish crosses are that I could raise in there. I can move it twice a day. The feed stores around here get cornish X so I can buy whatever number I want. I was thinking 8? I was going to do a few so I could learn without getting overwhelmed, before I dive in, build a huge tractor, and order a full "batch". Any thoughts?
