I've started a bantam coop this spring, and currently have 2 mille fleur d'uccles, 1 silkie (roo, probably), 1 sizzle, and 2 cochins that will be staying. I'm considering adding a few more silkies because my other one (who I suspected was a pullet) was killed by a hawk. Our coop is going to be based off of a 4'x4' dog house. The run is going to be covered and as big as we can manage, but will probably end up somewhere around 6x16. How many bantams can I comfortably fit in this space?
