Are they the same birds that had been drooping their wings, Shay? If so, I'm so sorry, they may not have been able to rehydrate and metabolize despite your best efforts.
If you can identify any of the survivors I'd pick them out and keep them out for a few days, just in case it's something communicable. Chilled chicks often have their immune systems compromised.
