I agree, my frizzle's will start getting their first upturned feathers around 1 week old. Some a few days eatlier, some a few days later. Theirs are 8 weeks? They should be frizzled alot by now.
No experience with sizzles tho.
Here's my 4 week frizzle for comparison

Now at 5.5 weeks he is frizzed everywhere but his head, no pic tho
...if yours were sizzles they would look like it by now, I'm fairly certain.
Again tho, no experience with sizzles, just frizzles...[/QUOTweek
Mine definitely don't curl like that. I think mine are considered satins
