egg color question

[beverlyl]

I have what I think are 10 Barred rock hens. I bought 8 of them from the pet store as barred rock and was given 2. My question is why do some of them lay very light brown/tan eggs and others lay a dark brown egg? is that normal? could they be crosses or .......?

I have LF brahmas. My girls lay everything from a dark brown egg, to a pink, to an off white. The eggs seem to get lighter as they get towards the end of a cycle and then they start all over again as dark brown.

What color legs do they have? If some are laying darker brown eggs they may be cuckoo Marans. Marans have white legs and messier barring while Barred Rocks have yellow legs and neater barring.
