no use having any thoery if the pigeons are not up to scratch,,,,,,,,every thoery is only a small part in the make up of a pigeon as theres so much else to look for in any pigeon than just a thoery alone !!!
for vallance thats getting along the lines of reds of dr rigg barkers i remember,,,but,,,had no white in it at all,,,dr rigg barkers where red all over,,,but,,,definately not chocolate
