Guys, I am new to chickens. I inherited 9 hens with a coop to fit them in freely. Hens are out of the coop into the fenced posture as soon as the sun is up and back in the coop when sun is down, so they only sleep in the coop. Floor is covered with the pine shavings. How often do I need to clean it? Do I "shovel" - dump all the shavings at once and spread all new shavings? Or do you rake the shavings - top of it and leave most of it in and add new shavings on top? If you do that, do you get the strong rotting smell? What tools most people use to rake these shavings, after all, its not a full barn where one can use full sized shovels or rakes, etc? Last, but not least, in order to compost those pooped dirty shavings, do you just dig a hole next to the coop and dump it all there? How often do you turnover it and how long until you can use it as a compost for your garden? Thank you.
