anyone have any experience with an automatic chicken house door? is it reliable? do some chickens not make it back in before it closes at night? how long would you be away and feel secure enough about it working as it should? what model do you have?
There is a bit of talk of them on BackyardChickens.com.
Chickenguard seems to get a lot of good reviews. You have to watch that you dont leave any stragglers outside when days change, the chickenguard addresses that. This guy does a pretty good talk on it. He had a lot of other vids on other topics too. My coup is pretty well sealed. I dont use a closer, just a pulley and a rope going to the outside, manual closing.
