nice side picture so you can see the color on their wings.
The male on the left has blue wing markings but the color of his chest is the same as his body. the hen next to him has a blackish bill and white bib with other white splashes. The male on the right looks typical grey but has black on his wings as does the front center hen. Of the two typical grey looking hens one has a violet/purple wing color and the other has the teal color as shown in the above picture.
Any help to identify the colors would be greatly appreciated, as well as any advice you would like to pass along. They are all very intelligent animals and I love them all no matter what their colors are.
