Pink Silkies. Yes it is real. My uncle use to raise birds and it is a color injection of food die they use to inject the egg. Perfectly harmless. You can do it with any bird. It last until the bird looses its down and the feathers grown in. They also do this with fish. ----- Yes boys and girls, It is like Flamingos getting their color from the food they eat.
The first time I seen an American Cormorant I called them "creepy ravens". There were a large number of them in a dead tree by Lake Michigan. The birds were dark, broody and craning their necks in odd directions for ravens. To the Google I went. Fascinating birds!
