Half-laid eggs?

I wish I'd seen this myself, but I really trust the person who told me about it.

My chickens don't like the next boxes I have for them, I think. I need to give them bigger ones. They always lay in them, though.

But he said he watched on chicken set on a box, and get up. He said the egg was partway out, and then it went back up inside the pullet, and she switched boxes, and finally laid it in another box.

I didn't know they had that kind of control! Sounds weird to me. I gotta build some bigger boxes, poor girls! (Especially before the BA's start to lay, they are HUGE!)
