I was reading on the Mother earth news page and ran across this: Although I raised chickens for many years, I never knew this helpful hint until my farmer neighbor told me. When your hen is sitting on eggs in her nest and you don't want any new roosters around, remove any eggs that come to a point. These are the male eggs. Let the hen hatch only the rounded eggs and they will all be females - no roosters in that batch! Anyone ever try this or hear it before?
