The DS was petting a Speckled Sussex hen. When he holds and pets a hen all the roosters come around so they can be the first to flirt with her when he puts her down. So when he puts this lady down, the black Ameraucana cockerel starts to do the courtship dance (as the DS puts it "I'm interested, I'm interested!"), at which she hauls off and gets on HIS back! This startled the DS (and the cockerel). Now he is noticing more of the Speckled Sussex are mounting the lower ranked cockerels. However, they seem receptive for the Speckeled Sussex cockerel, usually being willing participants in the usual hen role. The DS wants to know "Is this normal?" He has even named one of the girls Amazon.
