[CHICKENS-101] Re: boiling eggs

 

Hi Diana,
Very interesting. I've read that the shell is permeable. I wonder if the CO2 passes through the shell thus leaving a minute gap.

Of course this leads to more questions. What causes the CO2. I might understand if this were a fertilized egg. One might surmise that the chicken fetus gives off CO2, but I don't know if this is the case. So I guess the question is where's the CO2 coming from.

And speaking about permeability. I was talking with my neighbor that I read someplace, probably in one of the hatching papers that shells are permeable. Wonder how permeable - can a virus/bacteria enter an un-cracked shell.

It seems that the 'air' bubble inside of an egg is actually Carbon Dioxide and needs to dissipate for the membrane to let go of the shell and lay against the white of the egg. This will allow for easy peeling once boiled. A few days wait will help this to happen.
