I was all proud of the hard shell eggs my Barred Plymouth Rock started laying until this morning, when I found an empty rubbery egg shell in the coop. Now I'm totally freaking out that one of the others laid a rubbery shell and they ate it. Which means I may have to cull the culprit? Or could it be that once whoever laid the rubbery starts laying hard shell ones they won't eat it? Has anybody seen this kind of behavior before? I can't even begin to think of having to cull one of my fuzzbutts. I did not see any one of them with yolk smeared in their beaks. Could it be that a squirrel ate it instead? I've seen a squirrel coming out of the coop some days ago, and the rubbery shell is probably 4 or 5 days old. It was pretty dried out.
