Would you mind posting some more pics? If you could show the tail as well as the wings that may help. And a group photo would show how this one is different from the others.

yes, more pictures please. reason being, it's the different pace of wing and tail feather growth that may tell the tale.

edited to add, here is another thread with distinct pictures of the differences around this age.

I had 10 of them. I couldn't tell the difference between them till they were about 8 weeks old. When Reggie's comb started to develop.
