Hawkeye it's really hard to tell if it will happen again. I'm not familiar with silkies, but I do know it happens a lot with young pullets. It's really nothing to worry about, that is unless you are wanting to sell eggs. You don't want to turn your customers off. I've eaten a lot of eggs with blood spots. It's not a problem. An egg is about as close to meat as anything, and meat has blood in it.
Sometimes when the ovum separates from the ovaries in the hen a little bit of blood is captured in the egg. I wouldn't worry about it.
