I have both Golden and Silver Sebrights, as well as multiple sebright mixes (both golden and silver) as I am working on a mix-breed that involves the species. It also involves OEGBs, but I only have two of those that are pure, Silver duckwing and Red Pyle.
Here are my Golden Sebright/Silver Duckwing OEGB mixes
Here is a Red Pyle OEGB, Silver Sebright, and silkie mix
Here are three of my Silver Sebright chicks (Spock, Linnaeus, and Diamond)
Love 'em! I have a couple of silkies too! Still not sure how all of my pens are going to end up, so I may see some similar mixes as yours!
