Funny how animals were Blessed. Turkey have the ability to see colors and pick up quickly on the slightest movement while their hearing and smell is considered about as normal as any other wild bird. Pigs on the other hand see little color (which helps to define movement) but have an outstanding sense of smell and hearing. (no matter how bad they smell themselves)
From what I've read. Red & green LED lighting works the best at night. Even normal clear lighting seems to work OK if over time is brought up slowly to its full intensity over them. (pigs under a spin feeder or stand.)
Heartland of gun country. Fishing too.
