Egg Quality. Blood spots?

[Kaysea10]

Hello Chicken experts!
I had a friend of mine who receives my extra eggs send me this photo this morning. She just started a new carton of eggs and found this when she cracked three eggs. Two of the three had red or pink tissue. I’m used to seeing the occasional blood spot but this looks significant.
what do you all think it could be?
The eggs were laid within the last 7 days. I collect every other day. We do have some roosters. These did sit on the counter (unwashed) for a few days before I put them in the fridge but I thought that should be fine.

Definitely odd looking.
Had she mixed them up at all?
Did she save the shells so you can possibly ID the bird that laid them?
How old are your birds, in months?

Start collecting daily and put them straight into the fridge. Report back after doing this daily...see if the red stops.
