I've googled to try to determine which is which, but as far as looks, they appear to be the same...or at least to my "untrained" eye. Here's a pic of my guy.
One way to tell a dark blue (almost black looking) from a real black is that a black will have a sheen on them where as a blue (whether light or dark) will not have this sheen on the feathers.
Great thank you. He is so pretty, but I couldn't keep him bc I don't want to bother the neighbors. We will be moving in a couple years and there will be no neighbors this time!!
Thankfully my girlfriend took him so I can still see him. He came from the brightest blue egg.!
