I have some chickens with a mysterious briddled feather

[Chickensandhorsesforlife]

I have 3 ,7 week old Isa brown chicks and a 17 week old California white hen with a mysterious feather on their wing , and one has it on her shoulder.
The California white and 2 Isa browns have a orange and black one, and one Isa brown has a grey one. I am so curious as to what this is.

Any ideas?

Pictures? They're probably just growing their feathers in.

Pictures would help us understand what you are describing.

That's just them growing in their big kid feathers

Ok thanks. They have had it forever, so I was just wondering.
