Sorry for all the 'newbie' questions but I have four eggs left in my bator and although they are due today, i thought i would float test them just to see as i suspect they will go over by a few days. Did this in a nice humid bathroom and the temp and humidity hardly moved, 3 appeared viable, one i could even hear movement in, and the last also appeared viable but i am a bit suspect of it. It had what looked like tiny beads of water on it before i floated it, it floated like the others with about 15% out, and thought maybe the beads of water was humidity (currently 65%) but I also think it has a bit of an odor. If an egg is rotten - would it be blantantly obvious and float right up out of the water? I nearly left this egg out as i dont want an accident in with the other eggs that look fine, but thought i'd better replace it just incase it is okay. Any thoughts?
