I installed a new automatic chicken door on the coop yesterday, I use the light timer to open and close it. The chickens go in about 6:45 PM so the timer is set to close at 7:00 PM and open at 6:45 AM. Now that winter is coming on it will be nice not to have to go out and close and open the coop every day. I was going to use a remote system but the timer will work better when I am not at home. It worked great last night and this morning.
