I recently hatched out 2 males from a ? Able low %spalding hen and a cameo male, now by popular belief this make the 2 male chicks India Blue split cameo. My question is : at 6 months old, what color should their eyes be, not the tail eyes but the actual eyes in their heads? Mine have the bluest eyes but their 1/2 siblings ( same dad diff mom) hatched same timeframe already have the brown/green eyes. I wonder if the IB chicks eyes will stay blue and if so is this normal or a mutation of some sort? This is the first time I've had hatchlings and every where I ask no one knows the answer. Also they are getting green necks not blue,so I wonder will this change colors on next molt? They are huge for 6 month olds, bigger than my chickens and brave enough to fight a chicken too I had to separate them today.
