Raccoons are out anytime they know lunch is available. I've seen them as often during the day as night. We are a residential area but with a forest preserve at one end of the street - all manner of critters go by from fox and coyotes out in broad daylight to oppsosum &such. , this has been going on for 42 years - they all can't be sick. They just adapt readily to what humans provide for them - dog and cat food out during the day, bird feeders galore, garbage days when people don't put lids on the can or just throw food garbage in plastic bags (dumb).
