Any suggestions on cause of death?

[Silkiesocks]

About 3 month old Silkie, appeared fine, poos a bit runny. She smelt a bit funny (cheesy feet!?!) yesterday evening when treating scaly legs, but appeared fine other than that. Wasn't keen on coming out of coop this morning, and when she did, she just sat until she keeled over dead.

I've only had chickens since Octoberish last year, and this Silkie was hatched by one of my broody Wyandottes.

I also have 2 young legbars which I'm hoping don't go the same way - should I be vaccinating them against anything?

Any suggestions please...

It could have been so many things. Worms? Coccidia? These things cause runny poo and death if they go untreated too long. Without a necropsy you will never know for sure. So sorry for your loss.
