I have barred rock hens that i bought from a breeder and raised. They were the correct coloring and definitely look to be nice healthy barred rocks I bought a year old supposedly barred rock rooster from another breeder. He also looks like a barred rock. The only thing i would change is that he is on the smaller side for a barred rock I bred these hens and rooster and put them under a different broody hen but marked the eggs so i knew what hatched from what I had seven chicks hatch. Two have been black completely from birth. Two were born black with headspots and extra white on their breasts but have feathered in as light barred. The last three looked like normal barred rock chicks and have feathered in as dark barred. They are all now nearly eight weeks old So my question is does anyone know how i have this range of chicks? Are they some kind of sexlink? If so any idea on which are male or female? And what would happen if i bred any of these back to barred rocks in future? Sorry for the story and lots of questions... Im just very confused!
