Well, your 'idol' had a brain fart during his reply so I will fix it now. My brain, what is left of it, turned your Purple cock into a Violet cock so disregard the statement about having a Violet trio next year.
Put your IB cock to the side and breed the other two cocks. Put the IBBS hen under the Purple cock, that will make Purple hens and split to Purple cock chicks. It will also tell you if the cock is split to BS if they produce any BS chicks.
Put the Violet Pied hen and the IB Pied hen under the White cock. The Violet Pied will make both Pied and White chicks, the cock chicks will be split to Violet, the hen chicks will only be either White or Pied. The IB Pied hen will produce both Pied and White chicks in both sexes.
The yearling Violet Pied hen is showing a little Spalding that can be seen in the eye-liner and the barring on the tail. I suggest you find a Violet cock that carries a White gene for both of the Violet hens next year.
It is very rare that any pea is a 'pure' anything. White is called the great eraser because you can not see what colors or patterns lay beneath the white. For example, I am using a White Violet BS cock this year over Violet BS/Pied and Spalding Violet split BS. He looks like a plain white bird but I know that his parents were VBS/Pied and his momma was Violet BS/Pied so he has two white genes that makes him White and both parents are BS so he is also BS. Both parents are split to Pied so there is that possibility too. Good recordkeeping is a must if you are going to breed and raise peafowl.
Peas can go many generations before something unexpected pops up.
