I have heard that eggs can explode if bad or rotten. My muscovy was setting on her eggs and after waiting for them all to hatch she had 2 that weren't showing signs of life. So like I always do, I proceeded to open the eggs to see if the eggs just didn't develop or if they started to and then died. I opened the first one and nothing developed at all. I tapped on the seconded egg just one time and KABOOM!!!!!! I never realized the sheer force that a bad egg could have. I was outside behind the house and my husband could hear the egg explode inside the house over my screaming. It was like a gun went off. Thank goodness the egg had a fullsize chick inside that had passed away. I can't imagine the mess and stink that I would have had on me if it would have been all gooey inside still. Just thought that I would see if anyone else has had this happen.
