I have 9 older chickens about a year old in a coop I have 12, 8 week old chicks in the main coop in there own area 6 black sex link and 6 golden laced whyndot. Then I have 16 3-4 week old Easter Eggers and then 8 leghorns. I think I have 2-3 rooster chicks. I have my chickens free range no run and I’m wondering if each rooster will make its own little flock and spread them self’s out during the day or will they stay in 1 big group. 1 leghorn is for sure a rooster and 1 whyndot is for sure a rooster. Easter egger might be one not really sure yet. How many nesting boxes do you think I will need.
