I take the bottle, shake it and say. where's my girls where's my girls ! and shake the bottle, at first I got only 4 chickens out of 6 to go into the pen but those who did not follow soon saw there was goodies given out in the pen. they came running and then I closed the door to the pen. each time I do this they all come now, fighting to be first to go in and get dried meal worms, scratch or some other treat. LOL, I should do a video of it, maybe when I have some time this week ! I also keep the pen open so they can go directly into the coop to lay. then they come back to the yard, they love the pen, if its open so they can come and go. i leave it open so they can do as they please. I bought a white set of gates that close to make a kennel on amazon.com,( you can see it in one of my pictures ) I fence off my tomatoes and porch with it so there not going to my door and pooping on my porch, or eating my tomatoes. it works wonderful.
