Hi there, We have 8 hens (including one bantam), three of which are no longer laying and are enjoying their retirement years (4 yrs. old or so). I'd like to buy three chicks this spring to keep egg production up, but I'm wondering if our coop and run is large enough. The coop is a modified room in our barn that's 3x11 and the covered run is currently 5x12 but can be expanded on either side to make it up to 5x16. The roof on the run allows them to be out in all sorts of weather, including snow, as it doesn't really come into the run. They free range in our yard, but only when I'm around to watch them. Do you think we have enough space to add to the flock? Thanks in advance for your input!
