Bruce almost looks blue, a little dark to be a splash chick. I don't think they hatch that dark? But if the only colors in the pen Bruce came from, were splash and white, I don't know that it'd be possible for the chick to be blue? Splash x splash gives you 100% splash chicks. Maybe someone else will know better.
Love the foot feathers.

A silkie rooster will have small wattles even if they're bearded, but nothing like your typical non-bearded breed.
If the sneezing is random and not consistent, only happens once here and there, I wouldn't worry about it. If it's continuous, I would do something about it.Is the Amoxicillin for the sneezing? How do you know if there just sneezing because of dust or because of a cold? Mine do it often and just today I noticed my BSL doing it more then I like.
I'm not good with all these meds, but I started treating my birds by giving them VetRX, dropped a couple of drops in their mouth and nostrils. I also added apple cider vinegar (the organic kind, raw) in their water. Oxine did the trick when my birds started having runny noses and seemed to help for most of their sneezing also. What else did I do...? We treated the birds with Tylosin 200, injectable because the cold (or whatever it was) just wasn't going away. We did the Tylosin before Oxine, so I suppose Oxine was the most effective treatment in my case.
