Cuckoo Maran/Barred Rock ?

[First time Chick parent]

hmm...they both look pretty dark, so my guess would be pullets - in these breeds...dark = girls, lighter = boys. Barred Rocks have yellow legs, and the Cuckoo Marans have pink/white legs. Hard to tell from this picture - but that may help you out. Good luck!

I have exact same ones and the front one is the Maran and back one Barred Rock
