:lau No way! My 6 weekers that ended up being overwhelmingly male all started crowing last week...It's sounds like an awful chorus of nails on a chalkboard that goes on forever, and ever, and ever. Like the song that doesn't end.
If you're not super picky on breed you could check at a nearby farm store. Ours has had some older (3-5) week chicks every time I go in lately. They had some 2-3 day old AustraWhites I've got my eye on lol. I'm hoping they have some that get a little older where I can at least try sight sexing...
