Questions
1) Can Delaware really be a breed if it requires two separate lines to get properly colored males and females?
2) Is it possible to have properly colored males & females from one line?
3) If the honest answer is "no" to both questions above, then does the SOP need to be changed by either eliminated th Delaware enitrely, or by adjusting the description of either or both sexes of Delawares to something that can be produced from one line of birds?
4) How do we find the answers to these questions?
Frankly, I think the answer is yes to both of those first two questions. You can have "properly colored" males and females from one line, however, for the BEST colored males and females, you'd keep two lines.
