I have 14 hens, 3-4 of my hens are frizzle and or NN. I wanted more of the Friz/NN. I was considering buying more Friz and or NN, but then I remembered my rooster is Friz/NN (he is a smooth but carries the gene.) I will not have to buy any. The only trouble now is having to wait until eggs get fertile. I am glad he can help me with my obsession. This may not work for everyone, especially if you are looking for pures. I hope it gives people something to consider.
