Do you have a pen? You need to keep them in there pen so they learn to go into the coop at night, if not pen then you need to train them. I trained my girls early on to come when I call them with goodies in hand. They will follow me any where. I say... Where's my girls and they come running. They have been taught that when I say this I have treats so they follow me into the coop, or pen or where ever I want them to go. Then I give the treat. They go in to there coop or run on there own now at dusk, but if I need to leave and need them in there pen I just all them and in they go.
