When I raise CX I start them on Broiler and keep them there for the entire 8 weeks. Put your zip into Fertrells dealer locator ( http://fertrell.com/locator/) and start calling folks that show up. Dealers distribute to many feed mills and they are likely to know who is near you. If that doesn't work, PM me with your location and I'll see what I can do.

Ah shoot, I didn't think to start them on broiler feed. I'll start calling the retailers on that website tomorrow morning, thank you!
