LOVE Tillamook cheeses.. mmmm.. Extra Sharp Cheddar...
Back on topic..
I just got my CX butchered 2 days ago. They were on feed for 49 days (7 ish weeks) in a box stall. I don't have the tractor built yet, and I got dress weights from 2.8 to 5.5 pounds.
So it depends on what size of birds you want. Next time I am waiting a little over 8 weeks.
I was told by the butcher that these birds don't do well in weather above 80 degrees. While not a problem now, grrr where is my summer weather?, I plan on getting a fan or two for them once we get close.
