I am thinking about letting one hen hatch some eggs and have a question or two. I currently have my hens all mixed with two roos, a Light Brahma and a Welsummer. Can I remove the Welsummer hen and roo, let them be a couple for a while, and she will hatch Welsummer chicks instead of mixed breeds? Probably a stupid question but I know you would never let a pure bred dog breed with a mongrel then with one of its own kind and wind up with pure bred dogs. Do chickens work this way too? Obviously I am very new to all of this!
