i think the eggs are rotten

Place the egg in question in a bowl or wide glass of cold water and see if it floats. There is a tiny air pocket inside eggs, and over time more and more air passes through their porous shells and into the egg. As more air enters the egg, the air pocket grows larger, making the egg more buoyant.[1]If the egg lays on its side on the bottom of the bowl, it is at peak freshness.[2]If the egg stands upright on one end but is still touching the bottom, it is aging past its prime but is still safe to eat.[3]If the egg is floating, it is not a fresh egg. This does not necessarily mean it’s bad or unsafe to eat. You should test the egg by cracking it open and looking for (or smelling) signs that it has gone bad.[4]
