Oh And also Columbian (Silver/Buff/Red) and Birchin ( Silver Birchin/Brown Red...aka Black Copper) patterend breeds would be pretty easy to work with. You should be able to cross a Duckwing to a Columbian or Birchin patterned bird and all the chicks should be Columbian or Birch patterned depending on which one you used, and breeding back to the Duckwing should give about half Duckwing chicks
So of the breeds your listed you like which were, Plymouth Rocks, Wynadottes, RIR's, Cochins, Jersey Giants, and Polish, you could use the Wellies and/or Dorkings to get the BBRed color then of the ones you listed you should be a able to use
Plymouth Rocks ( Partridge, Silver Penciled, Columbian if you can find them, and if you breed barring into them from Barred Rocks, you could work on Crele colored birds which are Barred Red Duckwing.)
Wyandottes Same colors as the rocks if you can find them.
RIRs Are Red Columbians so they would be your best bet as far as getting the right colors easier you do the way I explained above for the Columbian patterned birds.
Cochins Partridge and maybe Blacks
Jersey Giants Black should work if you wanted to try but with blacks most of the time you cant tell if they are silver or gold based so I you can avoid it, I wouldnt try to use blacks with all the other colors that you could use.
Polish I personally dont like polish so I wouldnt use them and I dont know if any of their colors would help you.
And then also if you wanted you could add Black Copper Marans or Silver Marans to the mix. Those are Birchin patterned birds. ( BTW Silver Birchen and Brown Red are Silver/Gold inverses like I was listing in my above post.) Brown Red is the true genetic color name of the Black Copper Marans.
