On the topics of roost-time routines and the habits chickens teach each other: Langshan hens Bebe and Frida have recently combined habits to develop a collaborative evening ritual.
Bebe's been last to the roost ever since she found out a few years ago that crickets come out at dusk. Meanwhile, one of Frida's quirks is she
loves water on her feed. So much that, when there's only dry feed, she'll alternate between the feeder and waterer for a few beaks of food, a few beaks of water, food, water, food, water. Like so:
In the past month, Bebe decided she likes Frida's water/food habit, and Frida decided to start staying up late like Bebe, maybe because it's easier to go back and forth to the waterer when the run's less crowded (especially when Beakwipe [me] keeps moving the dish waterers further from the feeders to keep Frida from gunking them up with crumbs

).
They do this every night for 10-15 minutes after everyone else has roosted. By the time they roost, it's pretty dark, and I'm pretty bugbitten from waiting on them, but it's adorable to watch.
