I currently have 7 chicks in one 4x8 coop with an 8x12 run and of course I'm thinking of getting more. I'm wondering if it would be possible to extend the run and attach another coop to it for the new birds. Is this doable as opposed to building a new, larger coop to house the whole lot of them? Or is a third option to build a totally independent coop/run? What are your thoughts on these ideas?
