Ive lost 2 cockerels in two weeks. One was about 14 weeks old the other was about 23 weeks. I noticed both of them were ones that had hatch mates (hatched together and raised together) which happend to be one pullet each. I brought in 2 older roosters about 33 weeks old about 6 weeks ago. Ive never noticed any fighting between any of my roosters when Im out there. I watch them during feeding time too and there is no fighting. Im thinking they are probler getting older and of fighting age now I have had plans of butchering my unneeded roosters but they are just so small it would be a waist right now (about 3 - 4 lbs each weighed on a bathroom scale [my weight vs. my weight+chicken]). Should I pen up my older roosters together and let my others have the run of the yard or should I go ahead and butcher my cockerels + one of the big roosters?
