So this little one is a single hatch & supposed to be from all splash pen (but obviously not). This little blue marans is 8 weeks old. I thought for sure boy when it grew tiny wattles and has a pink comb at 4 weeks old but now 4 weeks later they haven't grown or gotten any redder. What do all you guys think? If its a boy when should the saddle & hackel feathers be noticeable?
