I have one girl (of 9) who is doing this (I believe it is only one). I have homemade rollaway nesting boxes. But my situation is that I am not here (my farm) 100% of the time. I have to split my time between my home and my farm until I retire. My egg 'gutter' (where the eggs collect) can hold a lot of eggs. The 'preferred' nesting box (#1 of 4) usually gets a good collection of eggs in that corner, causing the eggs to stack up just a bit, usually just to the wall dividing the nesting box and the gutter. It is here that I typically find an egg...or two...that have been eaten. This is a very new issue for me. To resolve the issue, last evening I blew out an egg and filled it with mustard. I placed the egg where I usually find the eaten eggs. As of right now, 3 eggs have been laid today, none have been eaten, including my "mustard egg". If it works, I will let you know!
