when i ordered from ideal they miss sexed two and sent an extra ten for warmth all males didnt miss sex those thou. we thinned the flock once because five got real aggresive. we have seven roosters left (yes i know too many). were going to thin again and keep two probably. so my problem is at times they wont shut up. ive read that roos will feed off each other and try to top each others crowing. when i thin the flock again will the others not crow as often or are they accustumed to all day crowing and cant be broken of this?
