My Icelandic chicks are four weeks old now and they are certainly little bundles of energy, more vivacious than any other breed I've had. Each chick is different and there are two comb types among the six chicks. I love the diversity.
None of them appear to have abnormal feathers. Does the fray problem show up with the first feathers, or does it happen later?
Good question, I was wondering that myself. Don't forget to post pics of your chicks!
