The police think that the animals were let out deliberately as the gate looked like it had been wedged open.
The deer are only 10-months-old and are running around all over the place.
The police are worried about the safety of drivers on the roads because the animals are quite big.
Danger to motorists
The farmer said: "If you hit one with your car it would cause serious damage.
"Because they are red deer they are very social and are found in large groups so you wouldn't just hit one of them."
Some of the deer have been spotted on nearby farms with sheep and it's hoped that they will be rounded up soon.
