Hi! I currently have 11 hens and 1 rooster. They’re all very happy! How we, I’m getting 20 more pullet chicks and 1 more rooster this spring. We have the roosters mostly for protection, but if a hen goes broody, I’d love to have her be able to hatch chicks. Does this ratio mean they are more likely to be less fertile? Should we get another roo chick with the 20 this spring?
