Roosters don't determine the sex of offspring, the hens doCould the roosters getting along also have to do with breeds?
My rooster (is a mix between a Hatch and a similar but smaller breed we call Habanero) likes to give us lots of roosters when the chickens hatch his eggs..., until recently I had him, then another one of his sons, now an adult that he constantly bullies (doesn't look much like him because the chicken he mated with was white he looks like a Hatch Giro), and then we had four other cockrells, that looked just like him, with which he really rarely bullied (only when they were trying to mount his hens and they hurt them).
We got rid of the four and we don't want to get rid of the Giro because he's super sweet and allows us to pet him and carry him around. Guess we might have to keep two separate flocks...
