Ok, so my youngest chickens (hatched in March 2012) had been laying regularly and then kind of stopped. I think they might have gotten sick, perhaps IB? They have a rattly sounding cough and are kind of hoarse when they try talking. My chickens got sick last year, and after all the research I have done though it was IB. Now, they have started back up laying with the exception of my two Marans that I got from a breeder. A few days ago, I found a giant soft shelled egg, which had been broken open and inside of it was a normal sized egg, which had also gotten broken. It is from one of my Marans because the inner egg was a darker brown color so I was able to identify it. I brought it in to the house and rinsed it out and saved it because it intrigued me. Today, I found the mother of all eggs inside the coop and it was fully in tact. It must weigh a pound and it is giant!! It measures about 4 inches long and 2.5 inches in diameter. I can tell it is from the same Marans. Tomorrow my other crazy chicken lady friend is coming over to take video footage of me cracking it open to find out if there is also a fully intact egg inside of it. Has anyone ever had any experience like this before? I have attached a few pictures for you to see. The broken egg on the left in the top two pictures is the soft shelled egg with the egg that had formed inside of it. It is harder now that I rinsed it and it has dried out. Can't wait to hear your input! Stay tuned for a link to the video on YouTube!!
