one week old silkie died

[Cindy2020]

I just came home to find one of my week old silkie died....it seemed fine earlier today they were all eating and drinking.
Was gone for two hours... so sad. Am i missing something?
the temp is fine they have food and water. No problems with the butts. Does this just happen?
I am new to this. Thank you for any input.

Sorry for your loss.... sometimes babies get parasitic infections and maybe was weak from birth....
