Anyone ever had a sterile rooster. I have started two batches of eggs in a bator with a Incu Therm plus for reference. The fist batch stayed in for 11 days. I candled them and nothing, So i took them out and broke them one by one in a bowl. Not a one had anything but a enlarged yolk. I started a new batch with 24 . After 12 days i candled them last night. I can't see anything. I think my rooster is shooting blanks. He about three years old.
