I have 10 Silver Spangled Hamburg Standard, and 2 Wheaten Old English Bantam eggs laid by my own chickens in my incubator! I have a Little Giant Incubator which has fluctuated somewhat but i candeled them all a few days ago and all except two were good, i got rid of the 2 and they were not even fertile! So now i have 12 eggs in my incubator and they all have the really dark middle with the air pocket on the end! I am really excited because they are due to hatch on my birthday which I did not even plan! I took them off the turner today and all look good! Cant wait to see what happens!
