I understand your frustration as well as your complication. We designed & planned our shed/coop for 2 years because we kept complicating things with this or that idea. I spent hours researching details like feeder height, roost height, door size, etc. In the end, the girls eat and sleep wherever THEY want, not necessarily where I planned for them to. Isn't that how it is? Maybe you could give your pullets hammers?
