I have 2 pilgrim geese that I hatched out- and thought they were both female. they both had lots of gray on them and now that they are really getting feathered, I am not sure. One is pretty solid grey, but the other seems to be developing white feathers instead of the grey ones "she " originally started growing. what do you guys think?? Do the males start out sorta gray and then turn white? (they are about 2 -3 months old.)
