I ordered a batch of Red Ranger meat chicks back in May from Moyer's. They were all cockerals. Here is their week to week growth in pictures. Subject A at 1 week old. Subject A at 2 weeks old Subject A at 3 weeks old. Subject A at 4 weeks old. Subject A at 5 weeks old. Subject A at 6 weeks. Subject A at 7 weeks. At this point I added a new test subject because Subject A was looking below the average size of the group. Here they are at 8 weeks. Both Subjects at 9 weeks. Both Subjects at 10 weeks old. I slaughtered before they reached 11 weeks. I didn't lose a single bird, no one got sick, all the carcasses were nice and healthy. I raised them in a tractor. Average dress out weight was 5lbs. I think I prefer these over the CornishX. They took 2 weeks extra to grow out, but they ate less anyway, so the actual feed usage is about the same. Much more active and healthy than the CornishX were for me under the same conditions.
