I am NOT judging anyone I just can't grasp the reason for this method. It just creeps me out and seems very unsanitary. My mom used to sort of do that- add bedding weekly and it would be 6-12" deep come spring but she then hoed it out in the spring and once a month all summer. The spring hoe out was god awful stink (no smell til you started hoeing it out) when I had chickens prior (30 years ago) I cleaned the coop to the bare floor every week and once a month in warm weather sanitized it Maybe I am just a germ nut but I can't bring myself to do deep litter.. Is there a really good reason TO do it? (aside from the heat generated from the rotting bedding) It seems like it would rot the coop floor out???????????? and can you pass an ag inspection with it?
