Well...at this point you have tried just about everything else LOL
If I saw that, I would worm.
You can use either Valbazen or Fenbendazole (Safeguard) to treat them.
Valbazen dosage is 1/2ml given orally, then repeat in 10 days.
or
Safeguard dosage is .23ml per pound of weight given orally for 5 days in a row.
Since you have quite a few chickens and you are stressed, it may be easier to use the Valbazen because of dosing once, then 1 repeat. It is a bit more expensive, but may be more convenient.
