Chicken sitting on top of other chicken on roost in coop

[Kaesi2020]

Hi all, this feels like it may be a ridiculous question and I may just need a little reassurance that it is OK. The coop cam shows my eight week old chickens lined up on their roost only one chicken is literally roosting on top of another. Does this happen sometimes? Should I try removing her? The hen she is on top of is not struggling to get out from under her. Here is a picture. Thank you!

Probably fine.
