Here is the link to the 1920 USDA Pamphlet we are discussing. I found it an interesting read and if nothing else a fun experiment.
I also read this pamphlet from the 20's and attempted this experiment.
I set 14 with egg cells on the side and 1 BCM egg that was so dark I could not see through.
I had 9 hatch alive and well. They are 3 days old now and I guess I will report back when we reach crowing age lol

I just read the same pamphlet last week and we are going to try it as well, why not??!! As people have pointed out nothing else has been proven to work so why not try something from 100 years ago, I am for sure! I think it was a fun read, and it will be a fun experiment.
Positive vibes...
