Someone on the poultry forum I belong to thinks that both Marans are females! It very difficult when you don’t have another one to compare them and you are just using photos. I am almost totally certain the Welsummer is a female, which is just as well looking at the size of a Welsummer cockerel. They have taken to perching on the edge of the box and watching me all day long. It seems even chickens get bored.
