I have a flock of 8 banties, nearly a year old. One of the silkies won't go up on the roost at night, and always wants to sleep in the nest boxes. The poor girl is a little out of it compared to the others (always gets lost from the flock in the yard, doesn't know to run when a hawk flies over, etc.). She's also definitely at the bottom of the pecking order. Any ideas for encouraging her to roost, or should I just accept that's she's kinda clueless and slow? Or ideas for keeping her out of the nests at night?
