Hello everyone, I'm just starting out my first flock. I have 14 eggs in the incubator that go into lockdown Thursday. I just got 3 white silkies that are just about a week old and though I've heard that they are next to impossible to sex until they are mature, I swear two of them are roos. They stand up really tall, and are super loud compared to the third one. The two I think are roos hate being held, while the other let's me hold it. Has anyone guessed this early on and been right?
