The lady said on wheatens if thier chest is all cream color then it's a girl. If there is any black spots or blue on its chest it's a boy. As far as eggs, you will have to wait for another 14+/- weeks for them to lay eggs. I can't remember right off hand how old they are. When I get home, i will look for you.
I have 3 mixed breed kids I should be getting so eggs from in late August. The Marans I think end of September and the Wheatens not till October.
It's this big one of the mixed breed I'm thinking is a roo.
