My flock (currently 1 roo 10 hens who stay in one flock, and 4 7wk olds that stay together and dont really hang out with the older chickens. i also have 4 2wk old chicks and 82 eggs in the incubators..) and i am worried that if i have multiple roos we will have problems. they roam about 5 acres of land ( i live on a farm ) and one of my chickens who isnt very well liked sleeps in a different barn than the other 17. (his friend chicken got eaten by the dogs ) they are NEVER locked up and are really good at laying in the nesting boxes we have in the two barns. if they have that much land and 7 barns, do you think we will have problems with roosters fighting and/or killing eachother?
