Well, they were naive chickens, a certain innocence gone, you mean? Yes, sad. A preening party is a pretty relaxed time, but even then I think the reason it's a party, all close together, is so some can preen and others look out at times. That's being a chicken.
I think when chickens see danger, they are wired to think that if they can see it, then it can see them. Which is true. I don't think they consider the rest of the situation around them, like being in a secure structure. Glass means nothing in this sense (chicken to predator: "Ha ha, you'll never get me through this hard glass! - said no chicken ever). Makes sense why rehabbers will put a special hood over the eyes of a bird they are capturing to help, because it calms them down a lot.

Maybe you could get some little sleep masks for everyone at FBA. Phyllis could have a nice fancy one with doily edges.
