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?!

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.

Hmmm....no idea!
