My chicks are going to be 7 weeks old and thinking about moving them out. Right now they live in our kitchen area in a brooder made of two plastic bins. During the day I take one plastic bin outside and they jump out and run around our backyard. Sometimes they'd play for a while, then gather in front of the French door of kitchen and "knock". In the evening, I call them by the kitchen French door, they jump into the plastic bin and go back to inside the kitchen. Now our coop is no where near our kitchen, but behind the house in the side yard. How do I teach them that is their home? I am afraid they are going to want to go back to our kitchen all the time.
