Good evening, This is my first post here, but I've been stalking the boards, reading posts for a few weeks now. I do not have any chickens yet (I am in my "research stage"), but hopefully I will be getting some later this spring. I have questions about various things and I would rather get advice from people who actually have chickens, instead of from books or websites. And I also have thoughts and will likely post some "just wondering" topics. Anyway, my first "just wondering" is about "breeding up". I read in a book that it is possable to breed up to pure. I understand how this idea works in theory, but I don't remember ever reading about this on any websites I looked at. So, I was curious if this a common practice or if it is frowned upon? It makes sense, I suppose, to introduce "new blood" to rare breeds. Or to increase traits like egg production, fertility, etc. But at the same time, too much of this would dilute a rare breeds genetics, wouldn't it? If this is in the wrong area, feel free to move it or what-have-you.
