    Doubt you can. I have 24 pullets of 25 weeks age. I had one blood-filled egg out of many dozens. [​IMG] It happens. [​IMG]

    If it's a little spot, it's called a "blood spot" or "meat spot." It's an artifact of the yolk detaching from the ovary follicle a bit soon. The "old wives tale" is that fear causes it, but it's probably caused by the hen jumping around when the yolk is about to detach. I think mine get them from jumping off the high perch in the morning - I get about 1 spotted yolk a week, and not always from the same hen.

    Some facts I found on the web about this:
    - Brown eggs are more likely to have blood/meat spots than white eggs.
    - Eggs in stores are carefully candled to get eggs with spots out of the consumer eggs.
    - Hens locked in laying confinement pens are not jumping around, and won't have them detach early.
    - The spots can fade as the egg ages, and grocery store eggs are not as fresh as consumers might think.

    This means that you will probably never see a spot on a grocery store white egg. If they bug you, you can pick them out of the egg, or just scramble the egg. It's fine.

    Found this in a university study........Pop

    Blood spots;

    The yolk is formed in the follicular sac by the deposition of continuous layers of yolk material. Ninety-nine percent of the yolk material is formed within the 7-9 days before the laying of the egg. When the yolk matures, the follicular sac ruptures or splits along a line with few, of any, blood vessels. If any blood vessels cross the stigma, a small drop of blood may be deposited on the yolk as it is released from the follicle. This causes most blood spots in eggs. After the yolk is released from the follicle, it is kept intact by the vitelline membrane surrounding it. The release of the yolk from the ovary is called "ovulation."
