hi.. i started keeping budgies with a single pair.. i have a green pied pair but both the **** and the hen have few blue feathers. the **** has blue feathers on its belly and its quite visible. the hen has only one blue feather near its tail. i went through color infomation but non of the sites mention blue on a green pied. they are dominant pieds. the pair has raised its first clutch of 4 babies and are incubating the 2nd batch. the first batch has 3 green pieds and one normal blue. the blue looks like a cobalt. is this possible from a green pied pair? wat mutation is my pair?
