We have a large 1 room shed on our property that we are going to split into 2 rooms. A 6' x 8' coop on one side and the feed shed on the other. I plan on building a roosting ladder (or 2). How many perches should I need for 10-12 chickens? Will they share the same perch at the same time if I make it wide enough? Also, this shed does not have windows. We plan on adding a window before winter, but for now can I just cut a hole out for the window and cover it with mesh and obviously plastic or something if the weather turns? My last question for now... I know that the chickens need about 4 sq/ft each inside the coop. Does this "rule" also apply for the outside run or do they need more than that outside? Until we get some fences and gates put up I don't have the ability to let them free roam just yet. So I need an idea of how much space I need for the run. Thank you so much for any advice! I'm new to all of this!
