The egg on the left looked like it has blood smeared on it, I could only find one other egg that was a bit dirty to compare to but you can see the color is more red on the left egg than the streak on the right egg, the rest of our eggs are clean.
I would assume I'm correct in thinking eggs should never have blood on them?
What does that mean, and what would be the next steps I should take?
There are 15 Black Australorp hens that are around 23 weeks old, about 4 are laying and I don't know which one laid this one obviously. They all seem healthy to me, but this is our first time having chickens so I'm not sure now.
Thank you
