Very few coyotes if any get out of an enclosure. Have more trouble with coyotes trying to get in an enclosure than out. Coyotes become democrats after the first month being in an enclosure. They have free housing and food. They live off the government (pen owner). Most pen owners ban the nuts on male coyotes. So if they were to get out they won’t contribute to reproducing. A lot of enclosures have high number of coyotes on the outside because when the females come in heat the males will travel trying to find them.
