Last year was my first year hatching, but I hatched several batches and got kinda used to what candled eggs looked like. So tonight, I candled the eggs under a broody I have. The first 4 I candled were infertile, or else newly laid and not yet developing (I think infertile). Then the next one was SOLID black. Now, I know in the final stages the eggs appear mostly black, but on this one I could not make out an air pocket. It just looked all black, from all sides... No clear at all. what does a rotten egg look like candled? Is this egg rotten, or about to hatch?? Any ideas?
