Boy or girl?

I have pretty good idea of what these are, but need a second opinion. These guys are all nearly 12 weeks old. The first two pictures are my Cochins and the last two are Orpingtons.

These I think are both cockerels. Would they be a splash and a blue?


This I believe to be a black pullet


This I want to be a pullet. Would it be blue?


And a black pullet?

I'm not sure but they are sure nice!! Hopefully someone who has more experience can help you. Lou

Agree, on clour and sex, with the possible exception of the lovely blue, second from the bottom. . . that might (or might not) be a boy? On balance it looks like a girl, but usually when I have doubts, I'm wrong.

I'm well known for entering a rooster as a pullet in a show, but I would agree with the choice of sexes reported above. I'm not as familiar with the black, blue and splash colouring for Cochins. Nice looking chicks though.
