please excuse the "Mad Max" mohawks...they were born 1st week of August....they have same shape feathers, same pinkish red (wattles)starting to show very different personalities...
the black one carries tail upright, silver one (Ric Flair) doesnt....Ric is slightly bigger than the black one....silver is shy, black isnt....any help very appreciated!
Side shots of the whole body would help. You have a white crested blue (first picture) and a white crested black (second picture), a silver laced polish is a white bird with black lacing on the feathers. Good luck with them.
