So I am 15.5 weeks in to my first backyard flock of hens. Briefly, we converted a Little Tikes playhouse into a coop for them, and used old 10x6 dog kennels for their run. I have about 4" of pine shavings in the bottom of the coop. Every other day or so, I scrape the poop off of the poop board, under their roost bar, and stir it around. Every couple of months, or so, I add more shavings. My plan is to take out all of the shavings next year, clean the coop thoroughly and start over. Is that the right way to do deep litter or am I doing it wrong...? It seems like it should be pretty simple, but I can mess up just about anything.
