My young buff cockerels, 4 weeks old now, are the most chill of my 18 chicks that I am raising together. They will sit on my lap as others are eating plants. I think they will make very good roosters.
I would definitely say it is a buff roo. I got 4 buff orpington chicks from YSC and they were labelled pullets and 2/4 are roosters. They are very pretty though and I was looking for replacement roosters for my 2 former roosters and so the buffs will be the replacements.
