Hello all! New to this thread. I have been trying to read many of your posts - which have been very helpful I must say. Anyway, I have 3 Isbar's that I hatched. I came out with one blue, one black and one splash. I am 99.9% certain the splash is a pullet. I thought that both the blue and the black were cockerel's. Now I am not so sure. The black is developing definite hackles, starting to grow tail feathers. The blue is not showing any of the same development. What threw me is that the splash has no real comb to speak of or wattles. The blue does have comb development but it is rather pale. The black has comb and wattles that are more developed than the blue and they are much more red. So I guess my question is, do the different color variations develop any differently? This group is is almost exactly 4 months old. Would love to hear everyone's experiences with development. Thanks!
