Can a roo and 2 hens live in a tractor together. I know that a lot will depend on the individual roo and hen. My little girl bought a Frizzled white hen and roo today and they are only about 3 months old. She wants to get at least one more for now and we want to build her a tractor. Are older roo has already tried to kill the little guy. (She put them in the pen before I could get there to put them up in the chick loft.) Thanks!
