I'm fairly new to raising chickens. I have 10 and at least half do not go for into the coop at dusk or even pitch black!?? I thought they would just naturally do that? Do I have broken chickens? They are about 10 weeks old and have recently been free ranging in the run. I can't see myself, chicken wrangling to put them in every night and the can't stay out due to possible predators. What am I doing wrong here? Please don't laugh!
