The tiny chicks were forced to huddle together for warmth, and were thought to be no more than a few days old.
The chicks were found abandoned in a field near Peterborough, in central England, on Friday.
Hundreds of newborn chicks found abandoned in a field in Lincolnshire have had to be put down, the RSPCA said, due to a case of bird flu nearby.
The one-day-old baby birds were discovered by a member of the public on Friday, running around in Crowland, near Peterborough. "And the noise was unbelievable", said Inspector Justin Stubbs of the RSPCA, according to the Wisbech Standard.
RSPCA officers are continuing to investigate how the chicks came to be there.
It's understood the chicks came from a nearby commercial chicken farmer but may have been dumped in the field by a third party. An unnamed breeder was said to be "fully co-operating" with RSPCA investigators.
Volunteers rescuing the tiny chicks.
Inspector Stubbs thanked members of the public for bringing cardboard boxes to collect the chicks and keep them warm.
"These tiny birds wouldn't have survived long out on their own at such a young age and in such unpredictable weather conditions", added Stubbs.
Local people helped round up the birds into boxes and a breeder collected the survivors and took them back to his unit.
The charity said it was possible that prior to being dumped, the chicks were being offered for sale.
