Its a bit on the pricey side BUT I won't have a coop without an automatic pop door..we have a pullet shut door..it has a photo sensor and closes at dark and the girls and I have adapted to it very well..I still check on them but if they miss the door closing they will hang out on the ramp and wait to be let in. It doesn't happen often and if you let them stay on the ramp and extra long time after dark that particular bird doesn't make that mistake again unless its the hardheaded girl we ALL have in our flock.
