A CRD diagnosis really needs to be made after some lab work because it has ramifications for other birds the survivors come in contact with even years down the road.
The symptoms you've listed could be any number of things that aren't nearly as scary as CRD.
How much tylan, how was it administered, how long did you use it, how long ago did you stop?
