I have had my solar powered, linear actuator automatic coop door, with a chicken night light in operation for a month now and it is working great.
All the credit of the design goes to Wick and his Heavy Duty Solar Powered Automatic Chicken Coop Door. It is a great well documented design. I took most of my inspiration from it adding a few modifications to suit my needs.
I used similar parts/materials to those Wick listed in his post. Adding a third timer and an LED strip light for a "chicken night light". Two DPDT switches (a momentary switch and a ON-OFF-ON switch). The additional switches added the ability to switch from Automatic Mode (timer driven), to Manual Mode (user input, up/down), and OFF.
This is the circuit diagram:
I mounted the battery, timers, and switches on a piece of plywood and enclosed it all into an MTM ACR8-72 Ammo Crate Utility Box.
This is a pic of the final product:
