So I set 20 eggs from my fridge that had been in there from over 2 weeks to a few days. These eggs were in the door in the egg cartons some were pointy end up some were down. I candled them about 30 minutes ago they're set to hatch on the 16th. Out of 20 eggs set 3 were not fertile at all and yeah I dropped one that had a chick in it. I have another post about that called dropped an egg. Anyway if anyone was ever wondering or guessing if it works to do this way yea it does it works great. My eggs are a cross between heritage Rhode Island Red and Easter egger rooster my other eggs are Easter egger rooster and French black copper maran.
