Neighbor had one so I was able to throw a few CX's on to see where we are at. Males were at 3.99 lb Females 2.75-3.14 lb Im about to open the 3rd bag of feed since getting them almost 5 weeks ago. Started with 12, have 9 now. These birds freerange well, infact they dont even finish their food in the morning before heading out in the pasture. 8 week mark should be good me thinks, although I could tractor them and pour the feed to them for some heavier weights.
