We dig a hole, far from the house, then crack the eggs to see what's inside. That way you can see what happened without the mess in the house. We had one from our five last eggs explode when hubby cracked it. Thank goodness we were outside, because I could not imagine that smell in the house.Well, never a dull moment. I am a rookie to trying to hatch eggs the broody way, so I placed some eggs from my boy's girls under a broody. She accumulated too many under her, so I decided to remove some this morning. Once I got inside, I realized one of the eggs sounded like water was in it. It wasn't water. I did an "eggtopsy" and as I tried to open it, POP. Needless to say it was rotten.At least I don't have to clean out the nest box.One mistake I will never make again.
