How do you get them to go in?
-Train them to recognize a container of mealworms or sunflower seeds by going outside during the day with them. Shake the container so they recognize the sound. You can also say the same thing every time you do it. (I shout, "Hey kiddos, what's up? Come get some stuff! I have some stuff.") [Others say boring things like, "Here chick chick chick" But I digress.] Once they come to see what's up, throw some on the ground for them. Do it for several days until they recognize the container and the sound and come running to you whenever you have it and shake the container.
-Then.... After they recognize the container and come running to you when you have it, take the container outside at dusk. Go into the coop/hen house, and shake it and call them until they come running. Throw some on the floor of the coop and shut the door once they all get in.
-Repeat until they get the idea.
