I read recently that chickens pass the mirror test but don’t really give a damn about their own reflection so the researchers had to use an alternative method to prove it. They found that lone cockerals don’t crow because there are no other chickens to alert, they will crow in the presence of even one other chicken but will not crow when left with just their own reflection, implying they know its not another chicken.
