if chicks are a month old with yellow legs that chick and all of its siblings are out of here....never to be breed in my pens. yellow legs is recessive so it takes 2 copies to express so if you have one chick with yellow legs likely they ALL carry the genes for yellow legs.
Good to know, Donna. She hasn't started laying, so we can sell her now with no damage done.

Marans are new to me and I acquired stock from several sources so that I don't need to stress over quarantining any new blood in the future and of course so I have more birds to choose from
