I know there is quite a discussion as to what material is best to cover the ground of a chicken run - cleaning the run is a job that needs to be periodically done - has anyone ever built a wire floor over the entire run - maybe a foot off the ground so that any poop would fall to the ground underneath - it would be similar to a poop tray that is used in many coops under the roost - with such an arrangement you just have to periodically scrap the poop from under the wire floor and dispose of it - the chickens don't have to walk on it at all - do you think that it would be hard for the chickens to walk on such a wire floor? - any thoughts on this matter - thanks
