I have a long wait for mine as they are only 10 weeks old but thought i would ask so i know what to expect.
I can't believe that at 37 weeks yours has not layed yet, well i hope you won't have much longer to wait.
I have 2 cochin mix chicks 11 weeks old. I think one is a boy so I'll be waiting a looong time for an egg from him!. I hear that they are not great layers but as far as when they start, I don't know. They sure are sweet and pretty though.
