I recently bought the Brinsea ChickSafe Xtreme coop door opener. It's been working pretty well for the most part, but three times now it's randomly closed in the middle of the day, locking the chickens out of the coop. I'm wondering if anyone else has experienced something similar or has any suggestions. (I did just email the company to see what they have to say.) I have it set to open and close via the light sensor. But today, for example, it closed while the sun was shining brightly, so there shouldn't have been any chance of it accidentally sensing low light. It was just installed about a month ago, so the batteries should be fine. Anyone else experience this?
