Beautiful but im new and have two with similar colors but not matching up to anything ive seen yet. Check out Dunlap Hatcheries they have images of chicks and adults and I saved the pages on my tablet, I carry it with me when I go to market. Let me know if you find out what they are. Mine are 2-3 weeks old now.
I think maybe a Golden Campine. I have one that looks pretty much just like it. I got her from a feed store out of the pullet bin and did not know what she was. I have done a lot of research trying to find out and still not positive, but she is starting to get more feathers now and I have deduced Golden Campine.
