Could anyone offer opinions on how to turn this chicken tractor into a normal, predator proof coop? We have 10 chickens of various sizes, including two which may have to be housed separately. My boyfriend and I made this chicken tractor for our meat birds and now that we have moved, we're using it as a temporary coop for our layers. They are not happy. lol We were thinking of taking the hinged door off of the top and going up from there. Or putting wire on the bottom and raising it off of the ground..... any ideas would be appreciated.
