Help, chicken struggling for breath

[Ellieolander05]

Hi, I have 2 cockrels and yesterday they started to compete for dominance. We noticed that when one of them tried to crow or make any noise it came out high pitched and squeaky, kind off like a whistle. Though he was still winning the fight.This morning they are still in dispute but the one without a crow still doesn't have it and I think he is finding it hard to breath as he cannot run or fight alot without his crown turning this reddish blue colour.he is also making a funny noise and opening his mouth like he is finding it hard to breath. I'm unsure what to do please help fast!!!

They need to nbe separated right away. What is happening now with the one whose comb was discolored and having trouble breathing? These 2 should be kept separated. How old are they? Do you also have hens?
