Could go either way - usually the hen's combs and wattles don't turn really red until they are a few weeks older. I have had some roosters combs start to redden when as young as 5 weeks, while some take 8-12 weeks.
His comb is very red and his waddles are already coming in... Is this typically for a rooster, the waddles to be coming in at 6 weeks or can this happen for a hen too? Also what age do they start to get their spurs?
