Have you decided yet which one of the roosters you want to keep?
The first does have rather long and very pointy spurs, I would suggest to at least trim the tips and file them round if he is going to be the one to stay.
The one in your third picture needs some serious rooster pedicure as well, of course only if you would want to keep him.
Until you make up your mind, just trim the tips of all the males and file them round to prevent further injuries.
Well, if the intestines were punctured/ripped by large and pointy spurs as in picture one, the fecal matter would seep into the body cavity and infection would start almost immediately and cause a nasty smell within a short time.
