Thank you. Sizzles are quite a heavy duty project so I love it when someone appreciates them.
Sizzles are supposed to have a deep mulberry colored walnut comb, just like a Silkie. But now that you mention it, I suppose I probably got some blue rose combs along the way. I'm not sure exactly when I got the first ones, but I can tell you that I'm still getting them as I just had one crop up in a 10th gen. rooster.
I'm sure you'll have a lot of fun with your Sizzle project & will probably learn more about genetics that you ever want to know - at least I did. However, if I had it to do over, I would buy eggs or birds from others that were a few generations ahead of me & had already gone through the rough spots. It would have saved me a lot of headaches! The first generation is very encouraging - you get some birds that are really yucky (though usually kind of "cute" yucky) & you'll probably get a few that are actually a pretty good representative of what a Sizzle should be. You'll think "Wow, look at me. I made a Sizzle!!" Unfortunately, it's all downhill from there & you'll be lucky to get much of anything even remotely resembling a Sizzle for the next few generations. At least that was my experience but maybe others have done better & will chime in about their Sizzle projects.
Also, here's a friendly word of warning. We all know that Silkies are addictive but I want to tell you that Sizzles are every bit as bad. Plus, to make matters worse, your Sizzle project is going to give you some adorable Frizzled Silkies, & they're just as addictive as Silkies & Sizzles. I hope you have a coop builder in your family!! lol
Here are some of my Frizzled Silkies.
