Chicken hiding under sister?

[violetgriffith]

Hi,
2 of our hens (H and F, opposite ends of pecking order) are really close, and at night they always roost together. for a while I have noticed H putting her head under F's breast/stomach and wriggling around. It's pretty cute, but I was wondering if this is normal? Thanks!

Yeah, kinda normal......hen is trying to 'hide'.

she's just trying to get cosy.

Is it the submissive one doing this? If so it could be regressive chick-like behaviour where they snuggle under mum to feel safe and warm. The other hen who is more dominant is taking on the mother role to the lower hen.
