I am new to backyard chicken keeping, and was wondering what to do about the chicken run. I've been doing a lot of reading on cleaning the coop, and want my girls (6 hens) to be healthy and want to make sure that I'm not missing anything. Their run is small at the moment, but we are building a new coop and run for them that will be much bigger. So far, the only thing I've done was add Diatomaceous earth to the ground, but it's rained here lately (SW FL) and it's beginning to smell a bit. Any suggestions? Hay, straw, bedding material?
