WHAT is this IN my eggs?!

[mlecreason]

The egg shells were clear of debris, but when I cracked them open, these 2 eggs had these things in them... What are they?!

Hmmm....no idea!

They could be blood spots caused by rupture blood vessels. Flighty birds are prone to them.

Looks like more than a blood/meat spot.....looks like piece of tissue on the left, can't really see what's on the right might be blood/meat spot.
This can happen sometimes, a piece of tissue sloughs off and gets encase with the yolk.
As long as it doesn't happen a lot, I'd not worry about it....
....tho finding funky in an egg will have you breaking them into a separate dish(instead of into pan or recipe) for quite awhile.
