Looking. What brand do you have and what is the most extreme weather it which you have it operating?I have a run chicken door that I have been using for about a year and a helf and have had to problems with it. You can also set the timer with your phone on their app if you need it to open or close at a different time than the factory setting which is 20 minutes after dusk and 20 minutes after sun set. As far as it smashing chickens goes if something is in the way of the door it stops closing and re-opens.
