It is common in the herds that breed this. Man are since blue eyes are big for pet breeders, so yes it is becoming more common. Then you have some herds like OCR that cull any blue eyes and to my knowledge has only had one in over 30 years. It should not "hurt" anything unless you get folks that do not want them. Some folks find blue eyes in a meat goat hard to kill as it is more of a pet at that point but not everyone feels this way and not every kid out of this buck will have blue eyes. Some folks also feel blue eyes come with eye problems which I have not found but it is something people will pass on because of this at times. Worse case you sell your blue eyes for pets no biggy. I would see how it goes and if need by you can replace him should it become an issue. I think you will be fine. So far it has never hurt me at any sale. People know a good healthy goat with good muscle when they see it, blue eyes or not.
