Is Muffin a Rooster?

[melannjur]

Hi,
We purchased chicks in May, including 2 Dark Brahmas. One seemed to be a runt (Muffin) and took a while to catch up in size to our other chicks, but once it did dark purple and green started to appear on some of the feathers, and the comb looks a little different than our other Brahma. We thought she was just rambunctious but are now thinking she is a rooster. Can any one help? I have attached 4 pictures of Muffin and one to compare to our other Brahma Massie.

Muffin, as in Stud Muffin.
Male and female Brahmas are different colors, males are black and white, females are penciled.
The green and purple sheen just means he's healthy.

Thank you so much for the insight!
