Thank you very much for your kind reply. I promise,they are real birds with real colors.
The subject of mutation is a life time study, and does not fit into this post. We are still working the finer details of it. However, I will be more than happy to share what specific conserns are for Gouldian fanciers. Ofcourse, if the answer will fit within my knowledge, otherwise, I will direct the questions to the right source.
My minor in college was Biology with emphasysis in Genelogy and gene mutations, and I am still learning from my birds everyday. My biggest lesson learned was to learn from the question, not to be fooled by the desire to answer.
In general:
Body color categories:
-Green
-Yellow
-Blue
Head color catagories:
-Red
-Black
-Orange
Chest color catagories:
-Purple
-White
These catogories each have several sub-catagories (such as pastel birds, as a sub-catagory to green or blue), and they are listed based on the dominance over the others.
Again, this is VERY general.
