This may have been addressed before, so excuse me if I am repeating history. I know there are people here who know blue very well. Let me start with some background info. I have a mixed flock of hens: Easter Egger, Cuckoo Marans, one Jersey giant and some Black copper maran/EE crosses (Olive Eggers) and several EE roos. Several months ago a dog got in the yard and killed a bunch of my birds, including my favorite rooster. So I spent the next week gathering all of the eggs hoping to get some chicks out of my roo. I got a very nice batch of chicks, including many that look like him! Now for my question. I had several chicks that looked just like cuckoo marans when they hatched. (They were black with white on their heads and tummies and they had what I call the maran roman nose beaks) Those chicks have grown into solid blue barred birds with blue legs. My very favorite of the chicks is a large blue barred rooster that has a pea comb and a muff. He does have a few red on the sides of his wings similar to a blue copper maran, but so far his head is all blue. I figured that because of the barring plus pea comb that they have to be Cuckoo Maran Hen X Easter Egger because all of my roos are EE. I cannot figure out where the blue came from. My EE roos are White/Red, all red with some blue/grey wing and tail feathers, and my favorite EE roo was red and black with a green tail. I know where the barring came from, but I can't figure out where the blue came from. I'm also curious as to what are your thoughts on the colors that my blue barred rooster might produce. Should I breed him to some of my black hens? I plan on hatching again later this year. I am planning on setting up two breeding pens and using two different roosters over my hens. I will have to take a picture of him and post it.
