I am looking to expand my flock this spring and am planning on building another coop. Currently I have a 8' long chicken ark/tractor that can house 6 hens. The ark has served me well and I really like the design. I am planning to go to 10 chickens and am deciding between building one big chicken house/coop to house them all or another ark that I will split the flock between. Does anyone have any insight into this choice? These are the pros/cons off the top of my head: One big coop will be only one coop to clean and maintain. There will be ONE food trough, ONE water bowl, ONE winter light etc. Two arks give versatility for flock separation for breeding, illness, troublemakers Two arks are mobile and can be moved around the yard. Thanks for the input!
