 The Food of the Gods (1976)

Morgan and his friends are on a hunting trip on a remote 

Canadian island when they are attacked by a swarm of giant 

wasps. Looking for help, Morgan stumbles across a barn 

inhabited by an enormous killer chicken. After doing some 

exploring, they discover the entire island is crawling with 

animals that have somehow grown to giant size. The most 

dangerous of all of these, however, are the rats, who are 

mobilizing to do battle with the human intruders.
