Hey gang and welcome to another DIFY video!!! I am so impressed with these ChickenGuard Automatic Lockin’ Chicken Doors I had owned 2 and I bought one more. They are a lil pricey but if I own 3 they have to be good. I did not mention in the video but the 4 AA batteries last as long as 6 months so far. I suggest if goin’ out of town and it has been 3 or 4 months to go ahead and replace them just to be safe.
