I raised CX, Colored Range Birds (from J&M), and Dixie Rainbows and Red Rangers from S&G. Next year it will only be CX and the colored range birds from J&M. My J&M birds all matured within 2 weeks, 80% were ready to process at 11 weeks. The other 20% were hens that were processed a week later. My goal was 4-5lb birds which the J&M birds met or exceeded. The size was very consistent even with our funky cool summer. The birds were free-ranged 8-12 hrs a day from 4 weeks until 10 weeks. The lesson I did learn at about 6 weeks is that they did require more feeder space than the CX. They were fed 2x's a day and I started noticing a lack of consistency in size, within a week of adding another feeder they were consistent in size again. This probably would not have been an issue if I had grain in front of them 24/7, but I wanted to encourage free ranging as much as possible.
