My question is can the male in my avatar be the sire of the yellow Delaware colored chick or is the sire one of these two Delaware colored males who are his half brothers? All possible sires and the mother are 1/2 Delaware, sired by my Delaware rooster, Isaac, out of different mothers. The chick looks like an average yellow Delaware chick with a single comb. The mother (yes, I'm 100% positive it's her because her eggs are distinctive) is Raven, my solid black Delaware x Blue Rock hen. Possible sire #1 is Rex, the Delaware x Barred Rock in my avatar. Rex is alpha rooster in that group, but his brothers do "hit and run" mating. Possible sire #2 is the Scout, Delaware x Easter Egger, with pea-single combo comb, meaning, it's not a pure pea comb, though it veers more toward that look. Possible sire #3 is Gabriel, Delaware x Rita (she is a red hen, BLRW x BBS Ameraucana with single comb). He looks like a Dellie with stray red feathers here and there. Mother, Raven: Possible sires: One reason I'm asking other than it surprised me that a barred rooster could produce a yellow chick like that is that I have an 11 day old chick out of Raven that is black with a barely discernible head spot, this one on the far right: Chick is not this particular one but looks exactly like it. Since it just hatched this morning, haven't gotten it out from under its broody bantam mama to photograph yet. So, can a barred rooster and a black hen produce a yellow chick, even though both parents are 1/2 Delaware?
