The chicken, in a separate cage within the wire trap, was unharmed.
Winkler says a person at Herman Baker Park on Sunday noticed the alligator. Texas Parks and Wildlife experts were notified. Traps were set Tuesday.
Winkler doesn't think the alligator "had ever been a pet, or that somebody released it." He believes the reptile migrated to the area.
The gator was being taken to a wildlife rehabilitation center for evaluation.
The park was to reopen later Wednesday.
