What is going on with my leghorn?

[BGcoop]

I have a young leghorn pullet(will be one late this spring) she has been laying for a couple of months but she frequently has eggs like this:

Not fertile that I can see(I have two roosters and all my other girls have fertile eggs) and they have this blood streak which is bloodier than any blood spot I’ve seen in my other eggs. Everything else about her seems normal.
Should I be concerned, and can I do anything to reduce this blood streak?(it’s just unsightly) Is there any hope she will eventually have fertile eggs-I would like to someday incubate her eggs.

I see that more in flighty hens. It's from a ruptured blood vessel I believe in the oviduct.

Yup, she is the flightyest (if that’s a word). Will it improve over time? Should I worry about her at all?

 

[oldhenlikesdogs]

It will improve if she calms down. I believe it's from them knocking themselves around flying off roosts or getting knocked about.

Ok thanks. Hopefully as the weather improves they will decided to leave the coop more often-giving themselves more space so she doesn’t “have to“ run away from the others so much. (They always have access to the run but pretty much refuse to use it when the snow is on the ground. DH doesn’t know it yet, but I’m hoping to add a covered portion to the run this summer to encourage them to go out more next winter)

Yep, blood spot.

I think it's explained in this excellent video, which is worth watching regardless:
