Again, this white only shows up on mine in the few weeks leading up to them dropping those tail feathers.
in order for the molt to occur, would it be okay to assume? that the blood supply is somehow cut back and the white is a possible result of no blood to those feather/s?
do the new feathers grow in colored? or do they re-grow again as white?
I tried looking up sickle feathers, and only come up with the fact that it's the rooster's outer tail feathers.
longhorn cattle have a color that when they are born as calves, they are red but this red can change over to a dark "parker brown" or even a black coloration as they get weaning age. so longhorns have 3 colors to work with, black, wild color, and red. black is dominate to parker brown/wild color, and parker brown/wild color is dominate to red. red is recessive. horses have just 2 colors, black and red. white is the absence of color which creates all the neat patterns.
but birds are a different world... so sometimes things don't translate exactly from the cattle/horse world to the bird world.
the sex linked chicken world is a whole new critter to me.. actually the chicken world is new to me, raising critters is not.... lol
the bielefelders will open up a whole new breeding puzzle for me...
