Im just reading what it says on the first page, the rules page, I dont understand why its a problem if someone offered 6+ eggs for the first three offers then offers one with only 4. It makes more sense than people offering stuff off their swap page, because that surely isnt hatching eggs or...
Yes it is, there are breeders out there with pure black and pure white, but also just because a bird is black or white doesnt mean that they wont throw other colors.
The Serama clubs are working on getting different varieties standardized and breeding true, you can show any variety of Seramas, but for APA and ABA shows only White and possibly black are accepted, and can go farther than best of varieties in those shows.
