I would appreciate those of you who are expereince to lend a little knowledge. I notice that most people incubate their eggs lying on their side. to be more specific, the eggs are placed in such a way that you would not find your chiken egss in the refirgerator rested on its holder.Is it absoluetly necesary to incubate the egss this way? Is itpossible to incubate eggs in a position where they are up right?
if i have been incubating my eggs upright for about three weeks now, should i leave it that way, or change the orientation to it lying down?
Also, has anyone ever had success saving any eggs that are mouldy? Or is it 100% that mouldy eggs will die or is already dead? if there is a way of removing mould, how do you do it?
