Genetics and egg color, mystery egg

[kellylake01]

My flock is as follows
7 serama hens
1 silkie hen
1 Cochin hen
3 EE who are as far as byc can see mostly cream legbar mix

I have someone laying light brown large eggs, and I'm not sure who it is, so I either have a very sore and overachiever or one of my ee isn't a blue/green genetics, if someone can help me with figuring this out I would greatly appreciate it.

I would say Cochin.

I'm pretty sure Cochins are supposed to lay light brown medium-large eggs, so I'd guess Cochin too.

She is definitely an overachiever then, this is the biggest and most consistent she has been in a very long time, thank you all for the help
