ok i know that if i cant find any self blues to use black. i have heard that breeding a self blue to a porciline can be deadly, is that true? i have asked before and have gotten several different answers (yes and no's). also has anyone ever breed a self blue to a porciline before and if so what colors did the chicks turn out to be(if you have pics please post)? i have seen in the what breed/gender is this section a colombian colored d'uccle, how would you go about getting that color in a breed that doesnt have it and what color's would you use to get the colombian color? i currently only have 4 chickens 2 pullets and 2 roosters. my 2 pullets are the porciline and the mille fluer, my 2 roos are a self blue d'uccle and a mille fluer oegb(his pullet was killed by a dog ) i have been around chickens my whole life but just now getting to the breeding part and eventually to showing my chickens so i am trying to learn as much as possable about breeding a good flock. i also know the best chance to a good start is starting with a good flock from different breeders who show (i still have to get the SOP so idk what the standerard is for d'uccle's so i post pics on the breed thread and ask them what they think). ~ this is a thread for anyone with these type of questions...yes i do want/need mine above answered please and thank you.
