I'm sorry, Im having trouble understanding your post, could you list out some information?
Age

Where you got them and when.
Brooder temp
Symptoms
What meds you've given them and what doses.
Pictures always help.

If I’m understanding right. You have chicks from TSC one died but you don’t know from what and one of the chicks is acting funny?

In addition you adopted a flock of fully grown birds and they are sick?

I agree with nuthatched everything that was listed needs to be answered to better assist.
