I have 4 flocks, 2 or more roosters in each, that are in a 150 x 600 ft poultry yard.@fluffycrow have you tried free ranging your two flocks together?
They usually work it out and stay away from each other.
There's also 9 turkey hens with poults. They have split into 2 groups and 4 singles. The group with 3 hens and the most poults are the ones terrorizing everyone.
Others who have kept CX pullets for breeding have found the restrictive feed makes the difference. Some commercial breeders of CX parent stock don't feed every day.Thank you.
And that's really interesting regarding the broiler pullet. Perhaps, through selection, they are like the Pacific Islanders or Scandahoovians of chickens. They're just going to be bigger. But if we look at your example, the difference between 8lbs and 12lbs on a 12 week old chicken is still a lot -- 33% -- that could be added by a broiler feed regimen. That's the difference between health and obesity.
