Do all chickens have the same number of feathers on their wings?

If so, how many secondary and primary feather should they have?

Most breeds have 10 primary and 14 secondary flight feathers, Some breeds like rhode island red and barred rock can carry two genes, Sf1*Sf1 and or Sf2*Sf2, that will cause the expression of additional primary feathers. The two genes are incompletely dominant. I have not read the paper on the subject so I can not post any more information.

I have a question, to satisfy my curiosity, why are you asking the question?
