chickens not going to coop at night?

[klf73]

I have some ameraucana with some mutts I hatched last May. Only one of the ameraucana(roo, go figure) has *fit in* with the mutts, other than that they are 2 separate groups. I think the mutt dom roo might not be letting them into the coop at night? I starting finding my favorite girl in a tree. I would pluck her out and put her in the coop when I go to lock it up. Then 2 other girls were out with her 2 nights ago. Then last night I had 3 girls and 1 boy in the trees. That is all the ameraucana that are separate but 1

. I am worried that some predator will get them, not to mention I hate going into the trees to retrieve them. Getting rid of the *bad* roo is not an option (yet). Maybe if I make a second door to the coop? Ideas? experience?

thanks

eta- they just started this, they went in with no problem since September

Mabey if chickens won't go in coop at night try putting them in at night and locking the door of the coop and keeping them their until morning.
