Fire crews were called to Booth's Garden Centre in Royton on 27 January after a blaze broke out in the single-storey building.
It was initially feared that all but three parrots perished in the fire but firefighters discovered that the majority of animals on sale at the centre had survived.
Oldham RSPCA branch manager Mandy Tierney was alerted to the incident by text message and took part in the rescue operation.
"I was told that only three parrots had survived but when we went into the shed it was clear there were about 100 birds plus plenty of chickens, rabbits and guinea pigs," she told the news provider.
I was so relieved - it was awful to think so many animals may have died so it was fantastic that it wasn’t as bad as we thought."
If a suitable and sufficient fire risk assessment is not carried out, the Responsible Person faces up to two years in prison or an unlimited fine.
The cause of the blaze is currently under investigation.
