Can roosters kill each other even with no spurs?

[Cedar714]

I have 6 roosters and 4 hens that are just 6months old now, so far no death fights but I have a couple of the favorite hens with almost bare patches on their backs from being tag-teamed.
5 of the roos have a date this Thurs morning which I am not thrilled about but it needs to be done sooner than later.
At least I found a poultry processor close by so I don't have to do it.

That's the sad reality! Most Cocks and Roo's will fight to THE DEATH over one hen. Mother nature taking her toll! I would split them during the day or have the injured one in the Coop while the others are out.

That statement seldom applies unless you are talking about gamefowl. Losses OP suffered are more likely a function of container effect (sloppy husbandry) or something going on not thoroughly understood such as health or other issues.
