Three of my five BRs have large red combs & wattles (one of which has a larger c & w and has had it for about a month). On a couple occasions one or more of them has sang the egg song while up on their roost. But I've gone through their bedding (and of course the nest boxes) and have yet to find an egg or any evidence of egg eating. Would they sing the egg song without actually laying? How long after they grow out their wattle & comb do they typically start laying? Edited: Oops, thought I was in the behavior section.
