Agreed. If we stop and think about how a hen hatches eggs, we would see that she "opens the bator" every time she gets off the nest for a break, or stands up to readjust herself. Connecting the dots, that should lead us to realize that shrink wrap takes longer exposure, or has other roots, not just opening the box.
Yes, we humans don't like lose ends or unanswered questions. We have a need for closure and this reason ties it all up in a neat little answer...
And, the fact that you are a successful, hands-on-hatcher, proves your point. Otherwise, you wouldn't have that high a hatch rate..... LOL, I would love to go through a hatch with you!
Wow, that's amazing.... People should try to never be too arrogant or high-minded to learn from somebody else experiences.....That last sentence is a testament to your character and maturity, 2 things some people never achieve! I don't understand some people's thinking process. We take eggs and mechanically hatch them (totally unnatural), but they want to throw that card and say it's unnatural to help a chick get out of a shell - they'd rather sit back and watch it die, because they perceive it to be weak, when in reality, the incubating conditions were not conducive to a clean hatch. Things that make you go, "Hmmmm."
....... I'm going to go meddle with my eggs!
