How to tell if your eggs are fresh

  We forgot to check the chicken coop for a few days and hubby brought these eggs back from the coop but I was a little worried we might have a rotten one. A friend told me a way to tell if my eggs are fresh  and here is how:

 Put your eggs in a pan or bowl of water. If they sink to the bottom they are good. If they start to bob or float they are rotten. That's all there is to it!
