It really doesn't look like a sunburn, its just like white flaky skin just on the very top of her neck. More like dry skin.

That is what I assumed on my NN, it comes and goes, mostly isn't visible, but will show up for a couple of days then go away again for a long time. I don't lotion them at all, just let them live their little chicken lives and I don't want to make the skin any less tough.It really doesn't look like a sunburn, its just like white flaky skin just on the very top of her neck.

Only one of my NNs have started laying. She is 23 1/2 weeks old. The other two have not started laying yet....(same age).Thanks, I was really hoping I didn't do something wrong. First time chicken owner, and I got her with a few other chicks that I picked up for my sister and she didn't want her. So I have her, she is so awesome that I took on another one, she's only 3 weeks old. So I was hoping it wasn't me since I have 2 now.
By the way, when do they usually start laying eggs? I don't really know much about this breed.
Thanks everyone!
Totally agree on all points, and I have never seen a sunburn either.Has anyone seen actual sunburn on NN? I have not.. the skin does turn red but that's been on mature cockerels/roosters and laying hens. Young birds and non laying hens have normal looking pink necks, no red at all... I also suspect they don't sunburn because some young birds can have really red spots on face/comb yet their necks are 'normal'.
I suspect the flaky skin happens on all chicks as part of their rapid growth, just not really visible on non-NN except as dander all around brooder, the room etc. Just an idea and have not done anything for it either.
Not sunburn at all, like kev says it must be the rapid growth,
