We are 6 days into having backyard chickens. We got 10 each 10 week old birds. They were all together in the same pen when we got them. I have a 5'x6' coop with a 8'x16' run. I built them a roost tack in the run and roost pole in the coop. I have 3 birds that won't go into the coop at night and I have to take them off the rack in the run and place them in the coop every night. Nothing is ever 100% secure but the coop is 100% secure and the run is pretty predator proof (I hope). I live in VA so the weather is nice in the evenings and over night. Should I place them in the coop or let them stay out overnight.
