For the tinkerers here I've decided to move away from the Ardunio Nano and ESP8266 to Single Board Computer (SBC) to control the chicken coop automation. Please spare me your tales of whipping out your CC and ordering a door. I went with the Raspberry pi 3 and I'm quite happy with the device and the programming. So much easier to program than the Nano and ESP8266.
I've tried to attach the code but can't figure out how so I put it in the message for now.
