I like them both, but A has more of a proud stance if that makes sense. I like the angle of his tail, and don\'t think it looks too high.
I\'ve had males that got their tail slower before and I actually like that. Helps me spot the males sooner. Those darn fast growing ones have fooled me into thinking they might be females.
I\'d definately keep them both. I have three splits from my last hatch, and I\'ll keep at least 2 of them. If you can keep two pens, that will give you at least a little more genetic diversity. I don\'t think you\'d have any trouble finding one a new home down the line after you see what kind of chicks they each produce....or until you get that perfect Lavender male!
