This morning I found the second egg like this under my roost. All other hens are laying in the nest. Hens have been laying for 2 weeks. The egg shell is broken in a perfect circle but the membrane is still intact and the egg is not eaten. I have fake eggs in the nest and I tried the egg filled with mustard. This morning it was completely gone. Shell and all. I have no problem culling the hen that is doing this if need be, but my last problem is that I don't know who is the culprit, or if there is one due to the egg not being eaten...advice please? Im aware that there are many posts about egg pecking, and I've already read through these posts like crazy, for days so now I am asking for custom advice from those of you who are more experienced.
