I have 3 yr old hatchery buff orpingtons. This morning I found a normal egg that appeared to have a very tiny squishy egg attached. Plus, it had a lot of weird looking chicken nuggety pieces attached. I knocked the icky stuff off and opened the normal looking egg. It was normal inside. I'm thinking one of my hens is starting to internally lay?? What do you think? There laying has been up and down for last couple of months with the winter weather, so I can't tell if production is off. I haven't noticed any of them looking sick. Is there anything I can do? vitamins? food? Is this the beginning of the end for one of my girls?
