Betty's flying ability is severely curtained by the frizzle. Her longest wing feathers do not have anything but stem on 1/2 of them. So therefore she is not nearly the flyer that Phyllis is.Is Betty a flier as well Bob?
Of course I am assuming that the frizzle gene has done this to her wing feathers. Sansa had this problem before she passed because of her weird molt. Betty came to us this way so I guess I won't really know until after she molts.
