Normaly if an egg floats it is bad and should be discarded. As the egg ages air pockets enter the egg, that's why they float. A change in buoyancy. If the egg is more dense then the water (or whatever liquid it is in), it will sink.

You have GOT to have mis-stated your question. If an egg is "hatched," it means you are talking about a baby chicken. They're NOT going to last long in in the fridge. If, on the other hand, you are asking about, local, fresh eggs, then I've an answer for you: it all depends on whether the egg as been washed. When a hen lays an egg, she coats the outside with amembrane (called the "bloom). This membrane helps seal the pores on the shell. An egg shell has around 6000 pores that let air in and the inside moistute to evaporate out. Commercial eggs are washed. Often, local, fresh eggs are not washed. An unwashed, refridgerated egg will stay fresh in the fridge for AT LEAST two months and close to three. A washed, commercial egg will go bad in about a month.
No, used restaurant utensils are not dangerous. As long as they are washed well with soap or high temperature waters, they should be safe to use. If you are skeptical you could always ask.
As the hen lays the egg,a protective coating called "bloom"or "cuticle"covers and protects the egg. Removing this exposes the egg to disease from bacteria and increases moisture loss from the egg. A fertile egg that has been washed will be unlikely to hatch.
Eggs should not be washed unless absolutely necessary. When the hen lays the egg she deposits a thin film called "bloom" on the egg to protect it from bacteria. It is preferable to leave this film coating on the egg. When the egg is really dirty they should be brushed to clean and when washing is unavoidable, they should be wiped with a hot damp cloth.
