My "good" chicks (LOL) also known as the Big Chicks, ( 10 and 12 weeks old) put themselves to bed, climbing an 8 foot, straight ladder since they were 6 weeks old. I trained them by putting chick feed, in their sight, on the rungs of the ladder, dribbling it ahead of them, until they went in. The next couple weeks I just let them see me sprinkle a handful of feed inside the chick door at bedtime. Now, they put themselves up, 1/2 hour before the "bad" chicks (LOL). The "bad" chicks are 100 chicks that share a chick house. They only have to go up two little steps to go in. Always, since they were babies, the last 20 or so have just about REFUSED to go in. The calls go like this..."Bedtime for chick chicks! Go to bed, chicks!" (the first 25 go up) Go to BED, chicks! (the second 25 go up). "Okay, I'm TIRED of this. You'd BETTER go up in the chick house!" (the next 20 go up). "Last one in's a rotten egg!" (No kidding...the NEXT 10 RUN and go up.) After that, it's start closing the door. The last ones run up to look...stand around, waiting for each other....finally go up, except for the last one or two, that I usually have to push in. Oh, yeah, and of the last 40, at LEAST 15 think they have to bite me, REAL hard, before they go to bed. I just tell them, "You're moving to the top of the list!"
