Why do my EE pullets do this when in the nesting box

It's actually their attempt to make the perfect nest. They're usually aiming to throw stuff behind them and to their sides to make a nice tight bowl around them. But with shavings, that's not easy, and instead it ends up on their backs.

'Tis why I use natural bedding of hay and straw.

 

It not just EE'S that do it, all hens do it. My bantams who set quite often do it all the time.

 

Our 1 RIR and 3 BOs have been laying for a while. We keep pine shavings in the nesting boxes and they like them and will scoot stuff around to make a good spot to lay... BUT our EE that is now just laying (less than a week) makes a PERFECT nest. So maybe you are right about EEs just being particular. I haven't noticed that she will flick anything on her back, but she does pay a lot more attention to nest making (and lays in the same box in a set of four in a row).

 

hens do that when they are laying or are broody,
if you just put some hay in a nest box, after the hen has been in there
you will see that she has made or atemted to make a nest,
i have a jap. bantam that will actually jump out of the nest and still flick bits
of hay and twigs on to her back, itsvery funny to watch.

All of my 22 pullets throw whatever bedding I have at the time in the nesting boxes over their shoulder onto their back, even after they get out of the box. Not sure why but it is normal if there is any such thing as 'normal'.

FWIW, I have used pine shavings, sawdust, grass clippings, sand, and alfalfa hay (current). There does not seem to be a preferred one...they toss/kick it all out.

 

My EE even pretties herself up after she's out of the nest box. She'll pick up a leaf or a bit of grass and put it on her back as she walks around outside of the coop, after laying.

I think it's more than just "making a nest." I think it's also part of an instinct to hide the nest, including herself. As if she were in the bushes, pulling in camouflage. Of course, that doesn't explain why mine does it when she's upright, walking around....
