How do I make an automatic door opener/closer for a chicken coop that opens in daylight, and closes at night?
My chickens are really good to me, they are keen to expore my garden when the sun comes up, then put themselves away at night. The trouble is, one night I forgot to close the door into the coop and they all got eaten by a fox. I've seen automatic opening/closing devices for sale, but they're really expensive. An example of these devices can be found on http://www.axt-electronic.de/index1.htm Any help greatly appreciated.
