Well, Coco also likes to peck Ginger off the roosting bar. And the peeper didn't really help with that. Because Coco knew that Ginger was right there just a few feet away. So she'd lumbar down the roosting bar like a gymnast down the balancing beam right for Ginger and drive her off.
So I wondered, if I divided the roosting bar in half with something so they couldn't see each other, would that work. And I think it just might. I didn't get home in time to watch them go to bed tonight. But they are exactly as this photo shows them from last night. Coco on her side and Ginger on the other with the cardboard divider in the middle.
The chick continue to grow every day. But it will still be months before they are big enough to roost with Coco and Ginger. So enjoy your separate rooms while you have them girls. Cuz the youngsters are growing up big and strong and they're gonna wanna roost with you before you know it.
