You could post some photos and maybe folks could let you know. Most little roosters get pink combs by about 5 weeks of age, most pullet combs remain yellow orange until they are a few months old, so if you aren't seeing any pink red combs than you might only have pullets which in most instances people want.
Sorry about your rooster, the predators always seem to get the good ones as they often go out to defend their hens.
