Mystery egg appearance

[Byrd gal]

I found a tiny egg today!! I have 16 week olds but is that a little soon? My biggies are close to 3 and lay normal eggs. Any ideas which one laid this?

What breeds are the young ones?
It probably is an early layer.

Could be a fart egg from an older bird, are any of the young girls reddening up?

One in particular she hangs around the nests. Has a red decent comb for her age. I have mixes not sure what they are. I should post and see. Supposed to have eggers Barred for sure and Reds those are easy to tell.
