Just an update as i know most don't, it's why I still seek answers. I rehomed the black silkies, I kept the Serama and the miniature white silkie. I know the Serama is male I was convinced from the start, he's trying to crow he's adorable. The white one never makes a sound. I was convinced maybe male, but it's way too quiet to be. New photos, of my little guys or girls.
Also they've been outside in a secure run away from my large breeds but my large breeds are actually being very "they are shouting why are you not listening" I'm tempted test them supervised together, is it worth the risk? Will update with photos shortly, on my phone sadly it won't show the photo before I add it so I can't find them.
