Lotsa- yours look a lot like mine, except you have some with darker hackle markings- but I think the tail would classify as squinchy- ???
Walt- Actually, they all had bright, bright yellow legs as chicks and juvies- they have all faded to a pale pearly yellow color, and I think what you are seeing is dirt. They are usually filthy little dust bathers. And they are excellent layers with wonderful personalities, so I think I will use the best three or four, add some fresh stock and a different roo and see what happens. My roo that died had better body type than this one, but he had the darker tail, like Kathy's Oliver. So I think some good genes are there - I don't want to give up on them, and I don't mind taking time. Building a breeding program is fun. And now I am getting a better idea of where to head- I think I am going to blow up the Schiller picture and hang it in my barn!
Also, another puzzle. Two of my hens frequently show more tail black and in a better formation- it seems to change with what they are doing - same with the tail set. Up, down, wagging, fanned - I assume you choose the tail set when they are most relaxed and at rest for the norm? Also, they had more tail black showing a few months ago than they do now- is that part of what happens when they molt at this age?
