You already have a door to the outside. Take the door and trim off, remove the nest boxes from the inside and build a box on the outside that will fit your nest boxes and reuse your door.
Have solar powered fence, solar powered indoor light and have a solar powered vent fan that I have not installed. I do run 110 volt 17in box fan in the run to move the air on hot summer days...
Lived in Norco, early 80's, 3901 Vine St. Property opened into the Prado river basin and we would ride our horses down there all the time. Ran into bobcats several times and one mountain lion and i do no the differance.
My dogs drinks out of mud puddles, my horses walk past a clean waterer to drink out of standing muddy water and my chicken make the water dirty in about three min. They are all alive and well and the chickens and dogs all eat horse poop:D
And that is the reason I will never live in a neighborhood that has HOA and covenants.
I think once the silt fence is removed it will not be noticeable.
