Checked a hunting calendar for Pa. and found this...
COYOTES: No closed season. Unlimited. Outside of any big game season (deer, bear, elk and turkey), coyotes may be taken with a hunting license or a furtaker license, and without wearing orange. During any big game season, coyotes may be taken while lawfully hunting big game or with a furtaker license.
Sucks to be a coyote in Pa.
A lot of states are that way for coyotes. Here in NM, where they have feral pigs, they can be hunted with no license at all. No bag limit. Just have to follow other rules (trespassing, safety, etc...).
