Hi everyone.... I have a pair of tiels.... the female is lutino and the male is cinnamon pied I think. All the babies are little cinnamons with yellow in the wings. I don't know anything about the parentage of the two I have. I've been told that any cinnamons they produce are female. Is there a good understandable reference for cockatiel genetics? I'm really intrigued with this and I would like to hobby breed. I have owned birds for years (caique, african grey, conures, lovebirds and cockatiels), but never educated myself on the genetics of cockatiels. Thanks in advance for any information you can give me!
