When I purchased my babies I told them I wanted all hens. Well I realize at one week this is difficult. Now they are 10 weeks and I think I may have the rooster. I got 4 different breeds. Marans, Speckled Sussex, Welsummer and Wyandottes. It it the speckled I am concerned with. My question is will he breed with all of them and if I choose to possibly keep an egg or to to hatch will this be a problem. I have read many articles on how to and everything points to hen except his waddle started growing way larger than his sis. Her is a pic of the one in doubt. Any help would be very helpful and thank you in advance.
