I did a search of old eggs, boiled eggs and floaters but couldn't find anything about this. I have some eggs that now float when put in water. I've been told that they are too old to cook. But they boiled up fine. other than being a bit rubbery. Are floaters safe to eat and can I mash them up and feed them to my chickens? Some of the boiled egg posts seem to indicate that old eggs are okay to boil.
