Blood on egg shell

[xx Georgina xx]

Hello,
I have found some blood on my blue eggs.
This is the first year my hen has laid and my question is...

Why do I have blood on the egg shell?

This happens from time to time. Something minor went wrong in the egg forming/laying process.

However, if there was a lot of blood on the shell and you continue to see bloody eggs for a while, then you may have a problem. But for now I wouldn't worry about it.
