Hi- For anyone that can help. We are new to having chickens. We built a (non-movable) coop for our 12 chicks now one month old. We are in the process of planning the run. I have been reading about the chickens and thier ground destruction over time. Is it ok to use pure mulch (shredded trees etc.. with no additives) to the ground of the run instead of them just using the ground itself? We are unable to move thier coop and run and so am worried about the possiblility of parasites over time. So I am thinking if I can put down a layer of mulch and simply turn and change it over time this will keep the ground in thier run area cleaner and prevent complications????? Would this be good to do or is it a bad idea??
