It would be interesting to see if the duds loose water at a higher or lower rate compared to good eggs.
so far mine are losing weight at the same rate... there are three that I am 99.9% sure are duds... the only difference I have noticed between them and good eggs is that one of the duds tends to feel like it sloshes a bit when I turn it.. another made a rather rude sound when I picked it up today .. I sniffed it to make sure it wasn't smelling rotten.. it wasn't.. but there isn't a chick in there that would make a low burping sound like this egg did.. sounded more like Homer Simpson after drinking a few too many beers.. lol
I moved all three suspected duds to their own bator... just in case one decides to go nasty on me when I'm not looking..
