Hi!! You have some beautiful chicks!
It's so cool how you just happen to get silkies when your daughter wanted some. And now you, like most people with silkies want it to be a pullet, we'll I have good news and bad news. Buttercup is a little GIRL!
Now for the "bad" news.....from what I can see your Lily looks more like a Luis
But not to worry, it is a little early to be completely sure, heck, something I don't know what my silkies are till they crow or lay an egg (and I'm good at this
) But buttercup is a girl and lily is looking like a boy, if you look at wattle development lily has a more than buttercup does. Also could you post some more pictures maybe next week so I can keep an eye on their development, and let you know if lily is truly a Luis.
P.s: Your little bantam is really pretty, it kind of looks like my partridge EE when she was young.
