Easy to use; integrated and fully functional automatic chicken door. Your door will automatically open in the morning and close at night by a timer set at the time you want. The automatic chicken coop door opener saves you time and gives you freedom; no longer rush to get up in the morning or shorten the night to close them at night, you can leave it at the door opener. That weekend nanny chicken is a thing of the past. Simple to install - no complicated wiring or cables required - powered by 3 AA batteries (included). There are no batteries in the package, you need to buy 3 batteries yourself.
