I have been searching thru past threads to get an idea for an automatic coop door. The threads that I have been finding all seemed to be dated 2 or 3 years ago. Can anyone recommend a auto coop door? Which ones are the most reliable, which ones you had trouble with. I am looking at purchasing one of the doors below: http://www.add-a-motor.com/Model D20 Motor for Chicken Coop Doors.htm http://www.automaticchickencoopdoor.com/ http://www.ebay.com/itm/The-2-in-1-...434?pt=LH_DefaultDomain_0&hash=item3375ddf0aa Please let me know what you think!!
