I have a flock of 8 hens. 4 hatched in August and 4 in March. They have integrated in the coop, run and when free ranging. The problem is at night. My roost has a door that swings upwards over half of it and is held open with a bungee cord. 3 older chickens sleep to one side behind a second door. The open section is guarded by a tiny little Araucana. I haven’t been able to close the door because the younger chickens fly on the open door and roost there. I have tried to get them to sleep in the roost. There is about 5 feet remaining in the perch, but the Araucana won’t let them in, she pecks and freaks out and they leave the roosting box. If the door is shut they just fly into the wall where the door once was. They are getting heavier and are going to have a hard time continuing to get high enough to roost on the door and I am tired of cleaning poop of the door. Fizzgig the Araucana used to be bottom of the pecking order prior to the new girls arrival and was the most difficult during integration. Any tips or similar situations?
