Ok four week pics.
Pearl is getting a peachy reddish color to her chest and some rust spots here and there though they are nearly impossible to see.
Olive
Ida who I am suspicious of since these are unsexed.
And Fern sexed as a standard pulled but smaller than some of my bantam ee's.
At week 5 Idaho is getting red patches on his wings. Pearl is still having color changes too but they seem more uniform than Idaho's.
