This may be a stupid question,but I have many coops to build in the near future.I do a lot of pre-meditation about ways to improve,or make me or the birds lives easier.One big consideration is a door,one that I can open and shut without getting into the coop.Sure,that is easy enough with a rope,but when I let the door come down, I want it racoon-predator proof,as in down,not being able to be pushed up,or any locks or hooks a racoon can figure out over time.
My idea,still not even on paper yet,is an up and down sliding door.I am thinking of a way to attach a upside down shaped "T" piece of wood,just above the very top of the door,when the door is down.Well,this won't actually be a "T" shape,,as the side closest to the door will need to be smooth,so when the door comes down,it will move these pieces over,continue past them until the door is all the way down,and then,by the weight of the "T" locking device,it will again move to a "centered" position,,where part of the "stop" will be directly above the top of the door,in the center of the track.In the mornings, I will need to have a way to pull this locking device over,to allow the door to go back up the track,but that will be as easy as adding one more rope.
Something very similiar to the shape of an upside down letter "V",,with a metal screw attaching it to the wall,as close to the door track as possible,yet allowing free movement of the door within the track,,you pull the piece past the door edge to raise the door,,but when letting the door down at night,once the top edge of the door is past the inverted "V",gravity will once again "center" this piece,,so the door cannot come up,and the locking device will be on the inside.
