For now I can only house 2 or 3 hens. Four will be my max. My intention is to have egg producers. I think I've selected a Buff Orpington and a Wyandotte. I could squeeze in a Silkie. I've been offered one at an awesome price. Do I need a Silkie? Is there an advantage of having another body to warm up a coop? I know they are pretty but Hubby thinks that Silkies are "useless" for us. Thoughts?
