if u take a White/black Barred bird and breed them to buff for about 2 generations you can get Buff barred birds... it is a hard color to breed and the hens don't show barring they just look buff... the boys sure are pretty tho...
looks like a dark blue to me... this happens allot if they are just breeding blue to black over time the blue's get darker and darker... if u breed blue to splash the blue's will get lighter and lighter... breed blue to blue and there will be some dark and some light and most in-between... it...
