Blue Silkie with Streaks?

[Kaelinstorm]

These just started appearing about a week or two ago. (I forget his age but I want to say he is about 17-18 weeks - Oh and Im guessing on the "he" part). He seems to have a larger comb and waddles and the mohawk looking poof. My younger ones (9-10 weeks) have smaller combs/waddles than he did at their age and their poofs are more... well poofy LOL But Sinatra sits on the babies like "he" is a hen Haha

Anyway, there seems to be buff streaks growing out on "his" neck. Is this a form of colour leakage? Or is it normal in say a roo (if he is - no eggs or crowing yet) Its pretty anyway. No I dont plan on showing him I just like to be informed about my animals. Thanks

Heres Sinatra:

It looks like gold leakage to me

Thats what I was thinking. This is just a colour "disorder" right its not some kind of indication of being mixed right? Sorry Im new with the purebreds. Normally I just picked out straight runs from mixed bins at TSC and local feed stores - bought on cuteness and egg layability (Haha if thats a word LOL) These are the first ones I bought specifically for the awesomeness of their breed.

Yep, leakage in the hackles. I had a few birds with leakage, I wasn't happy : (
