Hello, New to the forum and new to having backyard chickens. Just want to say that I've already learned a lot just lurking here for a few days. I'm looking forward to getting all set up and my 8 yr. old daughter is all excited to get started. I don't know who planted in her head she "needs" a few chickens to tend to. In planning my coop design, it seems reasonable to me to cover the floor of the coop with metal flashing material, with wood shavings on top. It seems this would make cleaning much easier and not have the soiled plywood floor. Any reason not to use metal flashing on the floor? Also, dumb question maybe but do they need access to water inside the coop if there is fresh water available in their run? I intend to close them in the coop at night even though they will have a fenced run...or is this necessary? Thanks in advance for any help and advice!
