OK, we've got a shed coop with two pop doors, because we have two parts to our run we can leave open or separate. Here's what both doors currently look like. This design has worked OK for the summer, but has clear design flaws I've found with regular use. The doors are hinged from the bottom, which makes them great ramps, but the space between the hinges and coop get filled with shavings and crap, making it a pain to close. I'm sick of cleaning this space every night and have a feeling with snow and ice it will be all but impossible to do. I need help with ideas for new door designs. I am also limited in construction tools and experience, so it needs to be something I can do with a non-powered hand saw and battery operated drill. I can get some help from my dad, but he's very busy this time of year and I'd like to do as much by myself as possible. My first thought is to use the same basic idea of the pop doors I have now, but install them from the inside (after framing out a door) with the doors swinging and latching from one side, rather than top or bottom. I have also looked at some designs that have a pop door that slides down from above the doorway inside, but those seem a bit more complicated for someone with little construction experience like me. Any other easy, practical ideas I should be looking at?
