Here is an outside pic of my coop with the run I just added. I have a small back yard so this is right in the corner. The coop is a 10X12 and I'm hoping I have room for 19 in it. I may need to give a couple away or if I have roosters... I'll have dinner. You can see the skylight on the left. I also have two windows on on the left and one at the back. It's warm/hot here so I have a fan hooked up to the vent that you can see above the door... it's hooked to a timer to run from 11AM to about 1AM. The brooder light comes on at 7PM and goes off at Noon when it starts to really get warm. I open the windows in the day and close them at night. On the right you can see where I can open to get into the 8 nest boxes.
