LOVE my white leghorns. You just may get used to the combs, if you give them a try. My girls are friendly, curious, beautiful, and my best layers. My oldest white leghorn was the first out of my 5 oldest girls to lay, and started at 16w3d. She laid every day for the next 17 days, and then she got an impacted crop from eating weeds that my kids were giving them, so we did surgery to fix that, and she started laying 3 days after surgery, and has been very reliable ever since.
There are rosecomb brown leghorns available from hatcheries. I've had one from McMurray and she was beautiful, but not nearly as friendly as my whites. I have no idea how well she laid, but she was beautiful.
