I am building a coop and am not sure how many chickens a I can keep in it. My coop will be 4x4x4 with external nesting boxes, and multiple roosting levels. There is also a completely enclosed run that is 10 feet long, 4 feet wide, and 4 feet tall. They will be also be allowed to free range in my 24x24 foot garden. Right now I have 3 random breed pullets (though I am starting to suspect 1 is a roo) and 1 bantam. If i do indeed have a roo I will have to rehome him. Then I will be down to 2 and 1. I have at least 1 ameraucauna egg incubating right now and would also like an EE. That would take me from 3 to 5 and I may have to provide a home for my moms frizzle leghorn, so 6 total, 5 big and 1 bantam. With the amount of room they have will that be alright. Do I need a door to that opens and closes from the coop to the run if the run is secured on all sides with poultry netting? If I wanted to when it gets colder out I could also insulate the run and turn it into an 'indoor run."
