Chickens sinus inflating/deflating when eyes closed. Normal?

[uktech]

Never seen this before as I don't watch my chickens sleep...but broody hen on camera, and I see this. And strangely enough only when her eyes are closed.

Infection or normal? She has never shown any problems or symptoms I can think of.

Can someone please give some advice on this?

Just noticed she is occasionally breathing with her mouth open when she's wide awake. Have not seen her do that before. She has been on her eggs coming on 26 days.

Eating and drinking as normal.
