A really nice feature of the ChickenGuard is that the light sensor is integrated into the control unit. Our other three door openers have a cable with the light sensor at the end, which allows flexibility for adjusting the sensor’s position relative to the sun. But if you have dairy goats, like I do, be prepared to replace chewed-up sensor cables. ChickenGuard makes this a non issue, because the light sensor is part of the control unit itself.
So instead of adjusting opening and closing times by moving the sensor — to get more sun exposure so the door opens a little earlier and closes a little later, or more shade so the door opens a little later and closes a little earlier, the ChickenGuard has both a sensor delay feature and the ability to combine the sensor and timer to complement one another. With the latter option you can, for instance, set the door to open at a specific time in the morning but close at dusk, whatever time dusk might occur.
The “Extreme” model is for anyone who keeps chickens in an extreme climate, such as Arctic Alaska or the deserts of Australia. It has all the same features as the “Premium” model, but operates at a greater range of temperatures — from 120ºF to -20ºF. The outer casing and inner components are constructed to military grade standards to withstand weather extremes. Additionally, for weather conditions that require you to use a heavier door than the standard aluminum door, the “Extreme” has a stronger motor able to lift a door weighing up to 8 pounds, while the other two models are designed to lift up to 2 pounds.
