Docile bird, Somewhat skittish, good layer

My red girl, Ginger, has always been patient enough to be held, but she does squirm and has pooed on me twice! I suspect in revenge. She is a good layer and fairly quiet and gets along well enough with the other chickens. She is 4th in the pecking order. BUT, she chases my poor ducks for no reason and loves to hover over their food even if she's not hungry. She's gotten to be a brat. We've nicknamed her "Crockpot" because of all the times we threaten to cook her. I suspect it's just her, because all my other chickens are very sweet and pretty much accept the ducks. They got their dominance established and pretty much let them alone. I also hear so many good things about other people with RIRs....oh well.
