I do daily poop management & add hay to their nest boxes that's it. My chickens do free range.My coop's floor is sand with pine shavings. I get the rake & a bucket. start raking up the shavings & notice they still look new. Finally, get them all out & the whole time I'm telling myself the shavings look perfectly fine. But I wanted to add some more sand to even the floor out. So, I added more sand, added some DE ,& new pine shavings. Cleaned the roost with Clorox's & swept the spider webs away. Moral to the story I think I'll wait longer next year I swear the shavings looked almost brand new after a year. OK , its done well here comes the gang their all huddled by the door BOK BOK & sounds I'd never heard before but they wouldn't go in. One thing is for sure chickens hate things to be changed.
