Yesterday I only got 3 eggs from my 7 layers which surprised me. I usually get more. Today 3 eggs again and broken shells and an obvious mess of yolk. Are the hens pecking the eggs or could it be a predator? I have recently put out some stuff from my composter for the girls since it was full of meal worms.There were some egg shells in there too. I might have un-intentually given them a taste for eggs. On the other hand, there is a squirrel and sometimes a rat in the run. Any thoughts. Thanks.
