If I recall correctly, a carrier is an animal or person who can carry a disease but might not show symptoms of it. Typhoid Mary was a carrier of Typhoid Fever, she never experienced the fever herself, but she spread it to many people.
Raccoons do not always show symptoms of rabies that are seen in dogs or other animals, but may still be infected and could transmit the disease.
From a Purdue newsletter in 2003:

Rabies may take a while to show symptoms at all, and is not a fast killing disease, so an infected animal can carry it and spread it over a number of days, potentially even weeks, before succumbing to it.
If you do not want to kill raccoons that are on your property, that is your choice. Many people here make some kind of living off their chickens, selling eggs and/or meat, and raccoons can decimate a flock in an evening, so many here do their best to eradicate raccoons from their property to protect their livelihood. 'Just build a better coop' isn't always an effective bit of wisdom because raccoons are fairly intelligent and can figure out how to get into even a secure coop. That will also come out during the day, daytime hunting is not a sign of illness, but rather desperation. Hungry raccoons will hunt during the day, putting a flock at risk. Night hunting is easier, safer, but if there isn't enough food around at night, daytime foraging is the only other option.
