If hatching any egg was as simple as some suggestions here, no-one would build incubators. Most of the comments are nonsense. Not one person has mentioned the fact that control of incubation RH is as important, possibly more important, than temperature control.
As pretty much all bird eggs require the same incubation conditions, so long as the bird will accept the egg(s), (they aren't too big, small or oddly coloured), any bird can hatch the egg of any another. Temperature required - 37.5C, RH around 50%. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
