Now that it's brighter a little later when I get home from work I've been giving my chickens a little free range time at night. They put themselves to bed when it gets dark and I tuck them in, say good night, and lock em all up safe and sound...but one of these days I'm going to totally forget. It's ALMOST happened a couple of times. If I forget and some thing bad happens to my girls I'll just die. How do you all remember to close up your coop at night? Any slick tricks you seasoned chicken keepers have to share?
