Confused about my hens

[Marinefam2053]

I locked up my girls tonight, and as usual perform a head count. One of my hens that usually stays away from the other girls at night has decided not only does she want to be next to the other hens, but she wants to put her head underneath her sisters. Why on earth would she do that? I have never seen any of them do that before and I’ve had them for 3 years.

It's a submissive behavior as well as defensive. It makes it harder to peck someone in the head if it's stuffed under your butt.

She needed cuddles. Like my girls who gently pick stuff off the end of each other's beaks, they are flock mates,

Duly noted.
My younger pullets do this to the few older ones that tolerate them.
