Lots of blood on egg

Hello,

I have chickens that are just over a year old. They are all very good layers. I usually get 5 eggs a day from 5 chickens. I am worried about one though. Today and two days ago I have found an egg with blood on it. To me it seems like a lot. The eggs aren't overly large. They are actually smaller than some of the other eggs we get. The chickens all lay in the same area so I am not sure who is laying them. I haven't noticed any chicken being out of sorts. I can post a picture of the eggs if necessary.

I hope someone can give me some advice.

Thanks,

Rebeka

sometimes that happen but can you post a pic? your "alot of blood" and my "alot of blood" may be very different
