Hi, I am very new to chicken ownership. Of the 2 straight run chickens we purchased one started crowing last week so we do have a rooster. The other 5 are pullets. What kind of a problem does this present once the chickens start laying eggs? Do we need to "candle" all of the eggs to see which ones we can eat? What if we don't want to hatch any? My husband insists that we need to candle all of the eggs because they will have chicks already growing in them. Not to sound dumb, but is this true?
