Hi, everyone! We're brand new to the chicken world and I think we've done well so far. We got our six "ladies" at a day old in late April so they're about 15 weeks old. Their pen/run is under our 16'x13' deck and their 8'x4' coop is inside the pen. Right now the "floor" of the pen is dirt, but we have an overabundance of flies. I've read many, many different suggestions on what to put down, but I still don't know what to use! In one article it says to use sand so they have something to bathe in as well, but then another says don't use sand because it can be ingested. We have pine shavings in the coop and that's been fine, but we have no tree coverage and pine shavings would just be blown everywhere. Does anyone here have any thoughts or good luck with what they use in their runs? We and our ladies, Annie, Caramel, Clarabelle, Fluffy, Luna, and Mabel thank you!
