I'm a little confused. I'm not talking about the effects of breeding birds too closely related, or the ill effects of raising multiple generations together (because there are usually none). I was saying that keeping a male for only one year is not enough time to accurately determine how well...
Here's the thing. Assuming you let them all mingle and free range all day, with little intervention when it comes to which bird you cross to who, the results might be undesirable. You might want a good flier and a good mother, but you end up with a good layer and a good flyer, with no brooding...
Be careful with that. You said that you want good free rangers. If by switching roosters you mean moving them from one pen to another then there is less of a problem, but getting an entirely new one every year can be. Hens can take awhile to warm up to a new male, which leaves you with even less...
Correct. But the term "established landrace" is very similar to saying "breed". An "established landrace" is just a landrace, and a landrace in the making is a selection of mixes.
No, that wouldn't be a landrace, would it? If I were the creator of the project, I'd still call them mix breeds...
Well, an established landrace would be considered a breed, so no. Even in its country of origin the landrace differs quite a bit from line to line, so uniformity is still far away
The color on the males is actually one of the main things I want to elevate from my line. This is not the color the males should have. Now, if you're asking about making a breed where the feathers themselves would be male-specific on both sexes, I have no idea
