I don't think it's worms, I don't know how they would have gotten them if you picked up newly hatched ones like you said, there shouldn't have been a way for them to come into contact with anything that they could get worms from. The stinky poop you describe was likely a cecal poop, totally normal.
Since you changed the temperature, have you had any more losses? I ask since you mention you just made that fix two nights ago.
Also make sure none of the lights you are using have what's called a "shatterproof" coating. It puts off fumes that are toxic to birds.
