My husband built our "pop door" for the pullets and unfortunately made it a bit to small, so it will have to be made much larger...For the time being he avoided giving our hens access to the run because we wanted to keep everyone isolated, but now they desperately need some outdoor time. (One of the hens gets to free range but the other is too skittish so the poor thing has been cooped up for weeks now.) It's just the two hens in a 4x6 coop with a nice sized roost and two nesting boxes, but they (especially the skittish one) need some more outdoor time. Today is the day that my dh is devoting to extend the run and to fix the doors. Right now the pullets door is pulled open with a string, there is a spring inside the door to spring it closed and a pulley system to open it. I don't really like it...the string always comes off the pulley, it's starting to fray, isn't always easy to open and I have a different image of what I'm wanting. Does anyone have pictures of their coop door to share or suggestions?
