Yeah if it continues to stand up straight like that as it grows I would say chocolate runner but if it ends up squatting like a regular duck then I would say Khaki Campbell.
But those pictures look more like a runner stance
For one, I would definitely say its an Indian Runner, I have had blue and black runners and neither looked like that. I am like 90% sure thats a chocolate runner.
and a very cute one at that 😂
