Whats the most likely mix of this egg?

How old are all of your hens? It doesn't sound like it could be the wyandotte or the meatbirds based on age (meatbirds lay late and yours are still young, and your wyandotte could not have laid the egg if she is still to young to sex), so it must be an EE egg. There is no way to tell which rooster fertilized it.

We never had wyandotts so we don't know the differences between them well enough yet. She is old enough to lay thogh. She's the same age as our silkie roo, and he's old enough to mate. The meatbirds are still growing. The two ees are experienced layers already.

Just because the silkie can mate doesn't mean the Wyandotte can lay eggs. Different breeds and different behaviors

I was just saying her age. I no longer believe it is a silky mix.

Yes, but you just said you know she's old enough to lay because she is the same age as the silkie rooster who is mating

Either way, could anyone take a guess at this mystery chick's mix?
She has no feathering on the leg, is solid black except for a little brown on the face (can't see that in the pic), dark colored feet with lighter bottoms, and came from a light cream/tan egg.

Probably an EE mix
