I have not seen anything like this "Fray" issue you peeps are talking about. I have hatched about 60 Icelandics I lost about 10 of them to the cold fronts that come through every now and then, like the one that came through 2 weeks ago, it was 22degrees and froze alot of the younger ones, I was out of town. But otherwise I have not seen this with any of mine.
I originally had 10hens and 2 Roo's which are the parents of all the other 30+ 2-6 month old ones I have still alive.
My NYD hatch ended up with 9 roo's and 5 hens... Some of the Roo's are lookers, but I do have a favorite one, I will need to get some pics after I get their new run finished.
I havent hatched any Ice's in a couple months but I have 2 broodies sitting on eggs right now though.
I had to slow down because I didnt have enough coops built.... I am slowly working on that though

Its being built along with fences for a calf soon, a 12x36ft horse barn and getting and learning about Honey bee's not to mention the goats kidding and planting our garden two times because of the cold front that killed it the first time.
its been busy on the Bryce Family Farm in Heber AZ but I wouldnt want it any other way. I simply love to work.
