In this vein, I say: get both.I think this is a great idea. Brown Leghorns aren't the breed my eye and heart love the most, but I was able to obtain really top quality stock from a top breeder in the US and I have learned SO much from them. You can FEEL quality when you put your hands on them, and I realized I had never experienced what a quality bird felt like in hand before. I'm not working hard on them, but I'm keeping them around as a quality benchmark for other breeds and they help me realize how far I have to go, and how much more important type and substance and vitality are than the things that we can all judge from pictures like combs and patterns.
A quality breeding group. (Rooster, two or three hens) and a run of NH Reds.
If the breeder is local enough, they are a resource. I'm sure they would want to see their line be successful.
Lessons learned can be applied to the NH Reds immediately.
