Here to vouch for deep litter and using pine shavings. I did that last 6 months and it was great. Cleaned the whole coop out and did it this time with coastal hay instead. That was a mistake. A neighbor vouched for it with the reason that the hay was cheaper but it does not work for this use. My only trouble with the pine shavings is that t when I took the pine shavings out of the coop and scattered them around for mulch it often molded on the ground surface. So I would then have to try to bury the pine shavings. But for the deep litter Stick to the pine shavings and adding the ammonia neutralizer. !!! No odor , warm coop, good padding for the hens jumping off the roosts in the morning too.
