No Eggs from all my girls in 5 days? help!

[Jesusbear7]

This is really weird, we have 10 hens who have been laying for about 2-3 months. We have a group of hens a few weeks older, but all had been laying pretty regularly last week. We were getting about 8 eggs a day, and started giving dozens away. We went out to collect this past week and no eggs. There have been no eggs since. We've searched the coop, to no avail. How could all of them not be laying. My leghorn was one of the first to start laying, then suddenly when it got real cold she stopped laying everyday and only gave us an egg like once a week. But now i don't have any eggs. The only thing i could think of is that maybe they are eating them, shells and all? I don't know. hopefully i can get some answers.

I have a couple of hens that kick eggs to the coop floor and once cracked they will all eat them. and yes they will eat shell and all!
If they are not getting enough protein in the diet, (they may be using it to stay warmin cold weather or during molt) then laying will suffer.
If they don't have 14 hours of light they will also stop laying.
