I have eight brahma bantams chicks 5 weeks of age. They are mixes of different types of Brahmas. I know the daddy is a dark and the momma hens are dark mixes. 4 of the eight chicks are mottled in color and I am starting to see iridescent feathers. Although they have these greenish feathers they look like pullets to me... combs yellow, developed evenly etc. Ever seen iridescent feathers in Brahma pullets? Thanks Picture #1: This picture shows the three main types of brahmas we have. On the left is a classic Dark Brahma Bantam (we are quite sure this is a hen, we have three of these) in the middle is a "mottled" Dark Brahma (we have four of these) and finally we have one Dark/Light Brahma Bantam. Picture #2: Here is another shot of all of them together Picture #3: This is a close-up of one of the "mottled" dark brahma's. The four chicks that look like this have one or two iridescent green feathers, along with a more "shaggy" look to them. Picture #4: This is Duck. We're 99% sure she's a lady. So cute! Picture #5: Another pic of the "mottled" chicks. Picture #6: A close up of our light/dark brahma bantam mix.
