Butchered my first batch of 21 CX this weekend, everything went very well and I'm super pleased. We had zero problems, no mortality and no leg problems. Basically 8 weeks old. Total feed used 335 pounds, total finished weight 108lbs chicken. This gives me a feed conversion fo 3.1 which doesn't seems to ideal. They free ranged the last few weeks of their lives and they had access to feed for most of the day. Does the ranging cause them to not convert as fast because of the increased activity? I'm sure I fed them enough, seems like feeding more emight have increased size but would have also increased feed used. This is the system I want to use so I guess I'm wondering if my numbers are normal and good or should I be looking to correct something?
