Unfortunatly right now I have ten hens and 3 roosters. They are only 5 weeks old. The original plan was to exist with 2 roos (incase one died or didnt make it out of the brooder) but the hatchery must have sent me an extra. I plan on free ranging, can I exist with a ratio of 10 hens to 2 roos? At what age should I remove the extra roo?
