Your hens must also be split. To get pure white chicks from a split white bird, the hen must also be split white. (That's like my neighbor's birds...) One of the peahens must be split black shoulder, otherwise you would not get BS chicks. (Sometimes a split BS will show some change in the shoulder pattern, but not a full black shoulder.) To get the pied chicks, one of the hens (not the one that is split white) must be carrying at least one pied gene. (If it were the same hen that is carrying the white gene, she would be visibly pied if she also had a pied gene.)
All 11 of the IB chicks will be carrying a BS gene from their father -- as will all the chicks he sires, including the whites and pieds. You will not see it visibly on any of those birds, but if they are bred back to a black shoulder or to a split black shoulder, some of the chicks will be black shoulder. Expect about half black shoulder chicks if you breed any of them to a black shoulder mate, and about 1/4 if you breed to a split. Half of the others (from the breeding of the two splits) will be split to black shoulder themselves.
If you can figure out which hen gave you the white chicks, and which hen gave you the pied chicks, you will know which hen has the white gene versus which one has the pied gene. I am assuming you mean the pied chicks have significant white on them, rather than just a few white flights and/or a white throat latch. If they only have one or a few white flights and/or a white throat latch, they could just be split whites and not carrying a pied gene at all.
Was this too confusing? Sorry. We can draw Punnet squares if you like. But the point is, the hens (at least some of them) must be carrying some hidden genes also, otherwise he could not produce the white chicks or the black shoulder chicks.
Congratulations on a great hatch from him!
