I cannot for the life of me get them to go into their coop by themselves for the night. When they were 6 weeks I locked them in there for a few days/nights then turned them out in their run. They are now 8 weeks old. They know their coop is the safe place and run in there when the dogs get to close. But it could be almost 9 and they still hang out in their run. I feel like i loved them to much because when I go in there they just flock to me and they definitely won't herd. I'm at a complete loss. What do I do? Pic of the coop and run.
