A few days ago, @KsKingBee posted this photo of one of his hen chicks, with a question about how often white feathers appeared in crests: That got me wondering about white crest feathers (and perhaps crest feathers in general)? And what the presence of white (or other) colored crest feathers means... More specifically, do white crest feathers turn up in birds that are genetically split to white, split to pied, and/or split to white-eyed, as well as to birds expressing those traits in the phenotype? And do all three of those genes do that? Or only white and pied, but not white-eyed? What else, besides white coloration, results in white colored crest feathers? And how commonly do we see a mix of colors in the crest feathers? And what is the effect of the black shoulder gene, either expressed or split, on the crest feathers of a hen? How light are her crest feathers? Will an IB BS hen without a white or pied gene have light colored crest feathers? Or blue as an IB? Or a mix of colors? My IB BS peahen has a mix of colors in her crest feathers, including one or two white ones, a few IB blue ones, and what look like mostly tan ones. (Although I suppose that could be dirt-coloring on white feathers ) See below (in person, they really look like they match the color of her neck feathers, I don't think it's dirt) I'm sure this particular hen is split to something white or pied based on her other markings: I went through the wonderful photos that @Blue Creek Farm posted of his trip to Taylor Hill Game Farm looking for crest feathers... Here's two photos (below) from Blue Creek Farm of a lovely purple BS SP hen with a crest feather mix of white feathers and feathers that match her neck feathers (the colored ones in her neck and above her beak): These photos from Blue Creek of the peach BS hen below show a crest with lightly tinted crest feathers that appear to match the colors on her neck. I can't tell for sure what color the rear-most few feathers are, but in the second photo, they look to me as though they are very lightly tinted, like the feathers in her neck around the darker patch. I don't think any of her crest feathers are white, but it's hard to tell from a photo -- although these photos are certainly beyond anything I'm able to take! (Beautiful, beautiful pics ) I had to enlarge the photos to see details... These midnight silver pied birds are interesting... the male appears to not have any white feathers in his crest. His crest feathers match the color of the back of his neck. The hen has lots of light colored feathers that I think may be white, and it sort of looks like a mix of colors, maybe? The rearmost crest feathers on the hen look as though they may be darker? (photos from Blue Creek): These photos of an IB BS WE (below, upper photo) and a bronze WE (below, lower photo) again show no sign of any light or white colored photos in the crest feathers, and the crest feathers appear to match the color of the back of the bird's neck. Interestingly, the bronze WE has a large white throat patch... and from the mating photo, lots of white primaries! (photos from Blue Creek Farm): The photos of the bronze WE peahen below (and above, below ) don't show any light colored crest feathers, although she has also has a white throat patch and what look like may be some white primaries (photos from Blue Creek): These photos of an IB WE below also don't show any white crest feathers, even though the bird has a small throat patch and some white primaries. I think this bird must be young, as I don't see a lot of WE visible yet. (Photos from Blue Creek): So far, I don't think I found photos of MALE birds with "mixed" crests. All the crests matched the colors of the back of the male's necks. I don't know if a male pied bird with white on the back of its neck would or could have white crest feathers. But the WE birds, even with the throat patches and white primaries, don't seem to have any white crest feathers in the photos I found so far. Even the male SP birds, which we know carry a pied gene, had solid color crests matching the backs of their necks. The hens are a little different... the BS HENS seemed to have a mix of colors in their crest feathers, again matching the colors present in their neck feathers. The hens that carry a pied gene also include white in the crest feather mix, the others don't. Like the male birds, the WE hens without the pied gene don't seem to have white in the crest feathers, even though they have white throat patches and white primaries. This is obviously too small a sample size to be able to state a universal rule, but I'm truly curious about this. I am beginning to wonder if it is only the pied gene that results in a mix of white crest feathers into a crest that is otherwise reflective of the neck colors of the bird? And whether only hens get the mixed crests? And if it is specific to BS hens to have mixed colors? I'm thinking that obviously a white bird will have a white crest, but it's not clear to me that a bird that is split white (as opposed to split pied) will have white crest feathers mixed in. But maybe I have looked at too many photos and am all mixed up? Many thanks to @Blue Creek Farm and Taylor Hill Ranch for the wonderful, wonderful photos.
