Are there photos of these tails we can reference with the above quote? I am having difficulty imagining a "wildly open" or "too open" tail. I believe the open or "tented" tail on a bird is related to width of the pelvis and hindquarters, and there are an awful lot of narrow back ends around that go with the pinched tails. These open and wide HQ lead to good production in hens, and yet there are also hens of all kinds of breeds and mixes with pinched tails that lay like crazy. It's a bit confusing, though I understand the premise behind open pelvis pointing to good production.I am still going by what I see on my faulty birds until I get a proper batch of marans. Of the 4 cockerels, two were what I think is too open, one seems to be listing to one side, and one is tighter, and I actually thought his was the best looking of the bunch. So you are going for a little open? Two of mine look almost wildly open. I have heard wry tail mentioned, but I don't know exactly what that means. The male that I showed you the picture of, whose hackles I thought were the most copper, looks like his hackle color will come in similar to yours. The other 3 will be strongly straw colored, but this one will have that copper to yellow back to copper fade. I know that my terminology is way off, but I am just learning, so bear with me. I am assuming that is what you refer to as the "halo". A halo is acceptable? If so, how do you determine a good one from a bad one?
