The bird attached with the other in the photo is definitely a smoky blue with grizzle (type of grizzle is open to question at this point). He's also carrying another factor known somewhat informally as "third bar". As for breeding those factors out of the young and getting back to wild-type (blue bar), it's possible, but I wouldn't hold out for it anytime soon. It also would depend on your hens, and the chances are that they all carry the same stuff as well. The bird behind your blue looks to be a light print grizzle. Are these Pakistani or Indian birds???? or European tipplers?
