The cock bird is a normal purple and all the cocks produced are normal, just the hens have the difference.
Just been out and took a few more pics.
The cock at the bottom of the pic is the father of all the other birds in this pic. The hens are sisters from a pairing with one hen, the young cock had a different mother. She can be seen in the nesting box he is stood on, she is a split blue and has a normal coloured chest.

Same two hens again, same young cock on box 16. The not quite coloured up cock on box 15 is brother to the young cock on box 16

Father and daughters hatched from the same clutch when paired with a YH PC/w GB hen (1st pic in a my previous post.)

The young cocks haven't got any full sisters, and the hens haven't got any full brothers so I have nothing to compare them to.
Cant get over the difference in the chest colour.
