Some of the smaller hens in the coop still don't like to go into the chicken yard yet. With temperatures rising, they needed a little more airflow in the coop. Instead of cutting another window in the wall, I built them this COOL new screen door so that they can have a HUGE "window" that they can see out of during the day.
The right side of the building is blocked off from the chickens so I can store feed, etc. But we didn't divide the building equal to the middle of the doors, so I had to make a little hinged section in the screen door to compensate for the extra width needed to close up the gap.
Because there isn't a center post for the doors to close to, I used large bolts at the top and bottom of the big doors, and the screen door, to hold them in place. This will keep predators OUT, and chickens IN!
