BCM cockerels should have NO copper on the chest, so all other things being somewhat equal I would keep the one with less copper. The only other DQ that would change that for me is comb sprigs; everything else they are too young to tell yet how they are going to turn out. Silly boy...crowing at 9 weeks. I'll have 3 cockerels that age in another week and I can't imagine them crowing, lol.
(Er, I'm no pro either...just my opinion.)
Actually the standard does allow for copper spots in the breast.
The French Standard allow up to 10% of the breast to be copper, the APA standard (See Below) calls for "a few spots". I like a solid back breast too but my culling regiments allows for some copper on the breast. The copper spots I seen in juveniles often disappears completely when the cockerel goes through an adult molt.
