I hope to make some real progress this weekend on building our coop. I had read and pretty much decided on setting it up for deep litter method until I read the thread on using sand instead. My coop is 12 x 16 and we hope to house 12-15 hens. Our coop is three feet off the ground with a dirt run beneath. The floor will be 3/4. Plywood. I plan to put vinyl down over the plywood. Is there a definitive preference between sand and wood shavings? In my situation I want to clean the coop as little as possible. I'm not looking for pets, I'm looking for eggs. Thanks. By the way out of that 12 x 16 we will have a 10 x 6 egg room so the coop will be 6 x 16 with a roosting area which is 6 x 6.
