Ravens prefer blue eggs

I had an interesting experience observing a pair of ravens in my orchard. I had gathered some eggs from my chickens that were blue, white and brown. These were in equal numbers. I placed them in separate color groups out in our orchard. The ravens soon arrived. They at first started to jump around the eggs and flap their wings, acting all excited. I guess this was to see if the eggs were alive or where a threat to them somehow. Next they threw dirt at the eggs. Then they approached the eggs and started to carry them off one at a time and leave them in other places in the orchard. The interesting part of my observation was that they first took all of the blue eggs, then the white and finally the brown. This made me wonder if ravens can see color.
