Silkie/Smooth Sizzle

[Christyna8]

Yes, but you are also applying the term Sizzle to smooth feathered birds, which by most definitions is incorrect. Even the site you refer to in screenshots contradicts itself on its definition of Sizzle on the very same page, at one point saying Sizzles are frizzled and at another point saying they are the same as Satins and smooth. When you posted about smooth and frizzled coming from the same parents, I simply assumed that you thought they were all Sizzles because they had the same parents and thought I would try to clear that up. That's why I brought up frizzled Cochins and the color Blue.

Frizzling won't ever breed 100% true unless you breed birds with a double dose, also known as frazzled birds, and that's not done because frazzled birds not only have brittle feathering and are often partially or fully naked as a result, but they also have a tendency toward having metabolic and heart issues associated with the frizzling gene. Breeding frizzled to frizzled results in approximately 25% frazzled birds, so it also isn't done by knowledgeable breeders. Typically, you would breed frizzled to smooth, resulting in about equal numbers of the same in the offspring. Thus, you will get both Satins and Sizzles from any hatch out of these birds. There is no breeding out the smooth feathered individuals.

Regardless, the standard considers any trait that breeds true at least 50% of the time to be true breeding, hence how Blue and Frizzle can both be standardized despite producing some birds without those traits when bred with like birds. You are correct, the first generation is not true breeding, but that has more to do with the overall combination of traits and not just frizzling, which is inherited pretty predictably. You have to worry about the comb, the crest, the extra toes, the beard, feathering type, feathering color, skin color, etc. Since the vast majority of these traits are heterozygous in your first generation, the second generation has a huge amount of variability even when that second generation is produced by breeding the first generation back to one of the parent breeds. This is why it takes many generations of selection for specific traits to get to a 'true breeding' flock, and as I said before, even that 'true breeding' flock will produce some frizzled individuals and some smooth individuals because of how the gene works.

Anyway, I guess that's far beyond the point of your thread and I can't really answer any of your original post's question beyond this Satin vs Sizzle stuff, so I guess I'll check out here. I would suggest you post about your bird's leg in the Emergency / Diseases / Injuries forum if you haven't already for more answers focused on that. As you've seen, here in the breeds section, we tend to focus on breeds and genetics so your other question was not really tended to as much. Best of luck!

Honestly at this point I think most of us are saying the same thing But thank you for this reply it was the best yet. Have a great day
