Yes. Something is wrong.
If it isn't heat stroke, then start with worming. Don't use DE. It won't eradicate a load of worms. The best it can do is keep down external parasites and is of questionable use (per studies) for internal worms.
I recommend treating with Ivermectin. That should address internal and external parasites, either of which can cause anemia. (If you overuse Ivermectin, the internal worms can gain a resistance, but if this is a new flock and first time use, it should be effective for both).
Silkies can be temperamental to raise.
Keep a close look out for further symptoms. The age is right for Marek's. That is a disease that Silkies are very susceptible to. It doesn't always produce the classic paralysis symptoms first. You can simply go out and find dead birds if it is internal organ tumors.
So sorry for your losses.
