Am I the alpha "roo?"

I have one little Mille Fleur d'Uccle roo with eighteen pullets and hens of varied ages and breeds, mostly standard heavy breeds (well, one may be an Iowa Blue cockerel, but isn't acting rooish yet.) The roo is a real sweetheart and I rarely see him even dance for one of the ladies, much less actually mate. The flock recently sufferd from one of the bacterial respiratory diseases and I handled all of the birds everyday to check their weight and to give them medication. Before this they were rarely handled (I mostly just sit with them and talk to them while they frolic around me!)

Suddenly the mature ladies have started to "bow" down to me when I reach out for them, a behaviour that I am guessing indicates submission??? I am just curious, since I never see them acting this way for the poor little roo. No wonder he has been giving my the stink-eye!
