So, I just picked up 2 new babies...a Dark Brahma and Light Brahma....that I will eventually add to my other girls making a total of 12 chickens. My inside coop is 6x8 and so is their outside run. Should I have more space than that? That's a total of 96 sq ft for 12 girls. Just want to make sure that when the new girls are added this summer, there's not toooooo much chaos!
