I know some people use tractors, but I wasn't able to because it is too cold right now and I need them in a coop that would keep them warm at night and because of that, I have to continuously put down straw and no matter how much I put down they still poo all over and stink so bad, and will lay down and poo.. It is kinda sad watching them too, they can't take more than a few steps before they have to lay down.. They do play sometimes and try to run, but not like normal chickens.. People that say they won't forage are wrong, they will and mine go crazy over bugs that they find in the run, but would much rather lay in front of the feeders.. I raised the red broilers before these and they are way more active, the red broilers foraged and ran around..
