Hen not laying eggs in nesting box?

[flockoffour]

I have a year old Ameraucana hen who has been laying since she was about 6 months. She has always layed in the nesting box and I have never had a problem before, until now. I'm not sure if the other hens are keeping out of the hen house, or what exactly could be happening, just that I hear a decent amount of bickering when someoen is trying to lay an egg. She recently started laying them in the bottom of the run of the coop, and I was wondering if anyone else has had a problem like this and what I could do about it?

Thanks

From time to time, some of ours will lay in the coop on the floor. Maybe they get in a hurry and can't wait for a nest to be available. It doesn't happen all the time.
