I am pretty sure the two dark ones are hens as well as the peachy red black one.
However, Stella the beige grey one with the yellow feet is starting to make me wonder?
I live in a town, hoping that is she is indeed a he that he will be a quiet rooster lol.
Any help is much appreciated!
Looks like its a beautifuly growing cockerel lol I just had a surprise very similar to your but there's always a chance for a hen but looks a little male like, were they all born around the same time
