I have some eggs under a broody hen and they are due to hatch any day... Unfortunately the hen has pooped and it's gotten on some of the eggs... AND I think I had a rotten egg explode (I say think because of another post - I have no idea what happen). Anyway - how can I clean off the eggs? warm water and a towel? I know they are porous so I don't think leaving rotten egg or feces on them is a good idea... But I don't want to hurt them by cleaning them off the wrong way..
