My Muscovy eggs have been working on internally pipping for near 3 days now. Yesterday the one started peeping at me. But still no external pip. I was going to do a small hole near where I see him trying to break through but the egg is so tough, any pointers?? I was using tweezers, and I think this may be why he isn't breaking through I am pretty sure the other has died at this point. He has a pretty crazy air cell, which concerns me more for him, too. please help!
