I had no idea these were causes of it that’s good to know. I always thought it was just something that happened occasionally and there wasn’t any rhyme or reason for itEgg yolks form and mature in the hen's ovary and sometimes when the mature yolk is released it may rupture a small blood vessel, the blood released will end up being encased in the shell, along with the rest of the egg contents. Causes of this can be:
- Incorrect levels of vitamins A and K in the hen's diet;
- Administration of the drug sulphaquinoxaline;
- Large amounts of lucerne meal in the layers' diet;
- Feeding stale, wet or mouldy feed;
- Continuous lighting in the coop;
- Frights, stress and disturbances.
Has nothing to do with a male being present to fertilize eggs.I don't have a rooster but I noticed I had blood in the yolk of 1 egg, what maybe the issue?
Mostly that is what it is.....unless it is happening every single egg or copious amounts of blood(but I've had that happen for a few eggs then stop).I always thought it was just something that happened occasionally and there wasn’t any rhyme or reason for it
