Hope someone recognizes the breed of chick on left that started out solid black with no markings, now showing some brown beside my barred rock roo. MysteryChick on left older now with gold breast(started out solid black). On right is what I hope will turn out to be Black Australorp. Near chick has arched tail feathers, both gold breasted chicks have these. BB, 'Bent Beak' is one of the gold breasted mystery chicks(started solid black with no markings). The beak twist is recent, don't know how that happened, but doesn't seem to affect its ability to eat or seem tender. This is an example of the curled tail feather, but I paid extra for one of these from the Pullet tank and both have the arched/curled tail feathers.
