Ok so I got 11 to start with and I know for sure one is a male but what about this one? So the one in the background is a Barred Plymouth Rock and that is for sure a female. One of the other Barred Plymouth rock is the male of the group and has a very red crest and is much larger than the female. But this one in front? I don't have any more of this breed to compare with. I am fairly sure this is a Blue Andalusian. From one photo I can find the females seem to have a fairly large crest compared to other breeds. But it is only a light pink crest not real red like the male I know I have. Oh yes they are about 7 weeks old today. My problem is Males are not allowed by city limits so when I deal with the other male I would want to do this one at the same time if it is male.
