Hen's behaviour before laying?!

My beautiful little Miniature Oxford Game Hen has been laying gorgeous little white eggs for about 2 weeks now. I've never actually witnessed her do it, but I know it's her as opposed to my other 2 as she's the only one who ever goes in the nesting boxes and she has bright red comb and wattles. She lays every other day in the afternoon usually.

My flock free range around my garden most days, and whilst watching them earlier I witnessed her dip her tail and wings and keep shutting her eyes slightly-as though she were uncomforatable. She's been doing that, and walking around slowly, for half an hour. She has been eating as normal and seems totally fine apart from that, but I was wondering if this is how Hens behave when they are about to lay? If it is then I'm going to appear really stupid!!!!!!

I know hens squat, and can guess what this means, but as I've never seen it I don't know if that's what she's doing!

Tried to pick her up her for a little health check but she ran off, her usual sprightly self!

So how do layers behave?!

 

Update.....

This morning I went into the chicken shed and she'd laid a soft-shelled egg on the floor. She is looking fine again!

Must have been giving her grief, poor thing. She's on the nest now so hopefully she'll be sat on a normal little egg, which I can have for my tea!
