What would make a hen lay two eggs in a short amount of time?

I have a hen in the house healing from an injury and when I went to let her out to stretch a little while ago I discovered she laid two eggs this morning. Does that just happen sometimes or is there something that causes it?

Were they normal in appearance? Sometimes an egg will get stuck in the chute and another egg will come up behind it, usually resulting in a problem. I had a hen become egg-bound, and after a warm soak, she "gave birth" to a normal egg, following an hour later with a shelless egg.

Both eggs were completely normal in appearance, and she's been laying one day for the last few months. I was just so surprised to see two in the dog crate today.

If those eggs were normal, and your hen is behaving normally, chalk it up to being just a fluke.

I don't know if I should post this or here sense I didn't start this thread, if I a fend I am sorry but I have the same thing happen to me today, I think??? only on a bigger scale, I went out and collected today and I had 28 eggs!!!!!!!! first I have never got more then 13 at a time, 2nd,... I only have 21 hens..... whats up with that??? I changed the bedding in nest boxes yesterday and didn't find any hidden, and I collect every day so no leftovers... I have never heard of this, course I am kinda new to my own chickens. ... I tried to post a pic of them but couldn't get it to load

is it really possible my hens laid them or could the neighbors hens came over for a visit?
would my hens even allow that??
and if so, should I give the extra eggs back?
