Hi, I am new here. It has been fun poking around and getting to "know" you all, but now I actually have a question... Why is there blood in the yolk of some of my eggs? My hens are about 1 year old. I used to have roosters, but got rid of the last one months ago. I used to think the blood was because it was fertilized, but since we still get some eggs with blood, I wonder why. Thanks!
