My experience is no.. unfortunately they continue.
You can see both blood and meat spot in the following article near the bottom.. what you're describing sounds more like meat spots..

Although the article says meat spots are more common in older layers.. For me they are more common in birds coming from TSC/Hoovers hatchery (even as pullets).. At least 1 bird from each batch I've bought from them in the last few years has had this issue and is why I won't be buying from them again. I've not previously seen or experienced it common in other hatchery's birds. But it really ruins the whole egg sharing experience for me, IF I can't tell who's egg it is. If I can tell, then I either feed those eggs back to the animals or cull the pullet/hen who's laying them.
