Ask anyone that owns Guinea Fowl why they like them so much and, I will bet the number one answer will be "They eat ticks and other small bugs." According to Stromberg's Catalog, Guineas are also great Watch Dogs, as well as keep away hawks, rats and snakes. We found with ours that they also sound off an alarm you when strangers pull into the driveway or walk onto your property. Now those are the type birds everyone should have around their farms and ranches.
There are several types or breeds of Guineas. While the body types are very consistent, the colors are a bit different.
Most people let their Guinea Fowl out to run about their property during the day. The birds really keep insects at bay, they eat them up! The protein is good for the birds, and who does not like the insect population cut down. They do need a place to roost and you might have to lead them to it each night. Most will of course go to that place when the sun starts to set. Your Guinea Fowl do not need a lot of room to nest, but they do need a thick perch and a dry draft free home.
Most people I know with Guinea Fowl feed them a chicken mix. Some add cracked corn. But mostly Guinea Fowl are foragers. They have even been known to eat mice and small snakes.
Some people are surprised to learn that Guinea Fowl do fly, but not too far or too high. But they sure will roost in trees and will sit on top of a person's chicken pens. Guinea Fowl will also sit on and go over your fencing. How tall is your garden fence? They love to eat fresh garden growth. They are also quiet talkative. If they are awake, they are making noise. Funny noises. Cute noises. Endearing noises and for some folks, annoying noises.
PLEASE DO AN INTERNET SEARCH, READ BOOKS AND TALK TO PEOPLE WITH OR THAT OWN GUINEA FOWL BEFORE BUYING THEM. GUINEAS ARE NOT FOR EVERYONE AND THEY CAN AND USUALLY ARE, QUITE LOUD.
As compared to other Farm Birds our experience was/is that Deron and I do not believe they are quite intelligent as other birds.
