Are these both ISA browns?

[Lessy21]

Hi,
We have just welcomed our first family chickens last weekend. We picked put x2 ISA browns, x1 Australorp and x1 white leghorn. The two ISA browns have different coloured wings and are slightly differing shades all over, I was wondering if that was a normal variation??
Thank you.

at this point, I think you have two isas (red sex links).

What you have to remember about Isa Browns, cinnamon queens, etc... these are all red sex links, which means they're all hybrids. Different hatcheries use different breeds in their mixes, but ultimately they're looking at making chickens that hatch out with obvious differences between males and females.
In this case, red sex link cockerels are yellow as chicks, and the pullets are pinky orange. I think after that first juvenile molt, those patterns on the one chick's wing feathers will go away.

Thanks for the helpful information Frazzemrat1, I was secretly hoping they may stay different as they grew but I maybe not!

Thank you both, do you think they will look slightly different when grown? Do you get to know them so that you can you tell them apart easily?
