She looks like a pullet. She has gradual color change from reddish color to white. She doesn't have splotchy colors like the first EE chick in this thread. She's very pretty. :)
Your buff orpington looks to be a pullet. The EE is definitely a cockerel. Easter egger pullets have a consistent pattern in their feathering. And if they are multicolored the colors blend gradually from one to the next. Cockerels have splotchy coloring and eventually get red splotchy feathers...
