You have circled 11 straight run breeds... do you have the space to accommodate that many possible roosters... or any additional roosters? I considered Wyandottes but read that they have a tendency to be loud and may be too pushy for my docile, lovely Australorp, Barnies, Sapphire Gem, and Speckled Sussex. Having had Cuckoo Marans before, they were probably our least favorite birds, as they aggressively pecked at us. Our Orpingtons were nice but I do not consider them the healthiest breed and (just my opinion) but I wouldn't pay to have an orpington that looks like a Speckled Sussex when I could get a Speckled Sussex and enjoy both its looks and personality.
