What door-proofing actually means
An automatic door removes one job — standing in the dark waiting for hens — but it quietly adds another: noticing when the machine has not done its work. A door that fails shut at dusk leaves late hens outside with the foxes; a door that fails to open at dawn leaves the whole flock shut in without water. Door-proofing is not about buying a better door. It is about shaping your own dawn and dusk rounds so that a failure is spotted within hours, not days, and so that the hens' own habits do most of the work before the door ever moves.
Set the closing time from your hens, not the sunset table
Hens go to roost by light and routine, not by the clock, and the last bird in is rarely the same age or rank as the first. Spend a week noting when your final hen actually goes in — a young pullet finding her place in the order is often several minutes behind the old girls. Set the door to close with a margin after that bird, not on her. A lamp on a timer inside the coop, lit before dusk, draws stragglers toward the doorway far better than any amount of herding, because the flock reads the lit coop as the safe place to be. Light-sensor doors follow the seasons on their own; timer doors need adjusting as the evenings draw in and out, and that adjustment belongs in your weekly round, not in your memory.
The dusk routine that catches a failure
Walk down after the door's closing time, not before it. Count heads through the pop door or a window — a torch beam swept along the roost is enough once you know your number. Check the run corners and under the coop for a hen that missed the door; a bird that sleeps out once will try it again, and catching her on night one is what breaks the habit. Glance along the run edges for digging or pushed mesh while you are there, because dusk is when the day's damage shows. If the door has failed open, close it by hand and make the note then, not in the morning.
The dawn routine that proves the door opened
Dawn's check is shorter but just as fixed: confirm the door is up and the flock is out and moving before you call the job done. Watch them come out for a moment. A hen who stays inside, sits fluffed or comes out last and slow is information you would never get from a door you trusted blindly, and it is the earliest warning most keepers get that a bird is unwell. Top up water while the flock is still near the coop and the morning round is complete.
The weekly once-over that prevents the failures
Most door failures are boring: tired batteries, a track packed with bedding and droppings, a frayed cord, a door warped by a wet week. Ten minutes on the same day each week — batteries checked or swapped on a schedule rather than on suspicion, the track brushed clear, the manual override worked once so you know it still frees the door — prevents nearly all of them. Keep spare batteries in the feed room, not in a kitchen drawer you will search in the dark. In KinsLe Care Teams, the dawn, dusk and weekly checks can each sit as a named duty for whoever is home that day, timestamped when done, so the flock's safety never rests on one person remembering.
