I purchased chicks from Welp in Iowa. They had a new offering of a 'Colorful Mix'. When I asked them the actual breeds, I was told that they are whatever hatched that day. Now they are 7 weeks old and are indeed a beautiful mix of colors, but I don't have any idea what breeds they are. They are far more skiddish than my last group and I am wondering if they will eventually get comfortable with human contact or not. Any suggestions? thank you!
