we just bought a very old homemade cabinet incubator and i wanted to test it out (for my own eggs next spring) with some cheap eggs, so i found out that fertile free range chicken eggs from the local Market have been known to hatch. i just bought 2 dozen and put them in today. Im gonna give it a couple of weeks then candle them and if nothing is happening in them then i have some one local who says they will give me some silkie and silkie mix eggs. Im so excited and i can't wait to hooked!
