My husband brought in an egg from our Roosterless flock. It was cracked so he opened it to give to the dogs but we found a freaky, embryo-like blob, complete with what looked like eyes. So much so that my husband (an intelligent man) insisted it was an embryo, but later conceeded it was probably a parasite. He threw it in the trash and it vanished. Like we went back to dig it out for a picture and an autopsy but never found it again. It was about 2 inches long, seahorse shaped, and white-ish gray. I know a pic is worth a thousand words, but none of the pics I've seen posted here of parasites look like what we had. Any other ideas?
