Chicken or quail have black or dark red spots on the meat Is this normal?

I've got about 10 quail meats and some of them have these spots.

Are these safe to cook and eat? Is it possible that they had a disease or were infected?

I'm scared of Coronavirus, and chickens and quails can carry influenza and Coronavirus is a type of influenza, so could this be related?



I've googled a lot but I can't find anything on it:
"Quail red OR black OR dark spot on meat"
etc.

My question is not a duplicate of: red spots on the chicken
It's just clotted blood.

Quail is a far more game-y meat than chicken meaning there is much more muscle and you end up with a lot of dark meat. You get the same with truly free range chickens.

This is nothing to worry about and I have never seen a quail which doesn't look like that.
