A raccoon had my hen by the throat about 6 weeks ago. The raccoon let go when we approached but ever since then there has been blood in this hen's egg yolks. Is it safe to eat these eggs? What could be causing the blood? She is 3-1/2 years old and has never had blood in her eggs before. Thanks in advance for your help. P.S. We now have hardware cloth on the coop and steel frames. Raccoon's can no longer enter the coop.
