hahaha yes I'm seeing the bird brain in this flock more than my past 2. I'll just keep putting them up I guess, glad to know its not just me lolWelcome to BYC! I've been there myself and still am at the moment. I had two girls that loved to roost in the trees as opposed to in the coop. I had two girls that preferred to sleep behind the coop on the ground. I broke those habits by putting them in every night.
And now I have 5 girls who would rather sleep on top of the coop just to make sure I have extra cleaning to do. Apparently, with all my current critters, I don't have enough to do according to them.
Continue putting them up and eventually, they'll get it. We use the term bird-brains for a reason. lol!
