I’m new here and not sure if this is the best place to ask....i have a mix of brown egg laying hens. This is the first year I have a rooster. I believe he is a Cochin. I want to add some Easter Eggers and Marans to my flock but not sure if the rooster will muddy their egg colour. Doing some reading I believe their blue colour will stay but any chicks that hatch will be Olive Eggers. Have I got that right? Should I keep them in a separate cage to keep the egg colour true?
