RIR are so Dark I just can´t see the black stippling in them.. and so far RIR x Black cross I have seen the chicks seems to lack Db(they are just black, not brown)Black Tailed Reds carry Db/Db where Reds are Co/Co
Breeders of Reds as well as Henk69 recognize them as a Red Columbian and not a Black Tailed Red.
Chris
but as far as NH are concerned, they look Black tail Red to me, but they could be Co, and Di is also a columbian restrictor, that could be helping restrict the stippling on the hackle and saddle
this are the "Known" Columbian like restrictors..
