monster eggs

[big greg barker]

Hi,
I have some chickens in one of my pens that are laying some big honking eggs. Double yolkers and then some. I haven't been too concerned until today because there was blood on one of them. I can't figure out which birds are laying them.
I have buff orps, white rocks, gold wyandottes, and golden comets in that group. I don't think the rocks are doing it as the barred rock pen doesn't have big eggs, nor do the SL wyandottes. That leaves the orps and comets. Any ideas as to the cause, and how to help stop it?
They are getting as much layer pellet feed as they want, I have started feeding corn for the colder weather, along with BOSS. Also oyster shell, and all the water they can drink. The flocks as a whole (37) get a loaf of bread between them most every day as a treat. Also veggies scraps from the house. They eat better than we do.
They are laying collectively about 28-32 daily, except when we get the big ones, then the number is about 24. Any suggestions are welcome... Greg

I am not knowledgeable enough to comment on all your questions, but as far as laying the big egg, my bet would be on the comet. We have one and her eggs are ginormous. Makes me ache for her every time we collect one.

I have a comet that lays a huge egg. That would be the one I would keep my eye on try to catch her in the nest to collect her egg after she lays.
