I got mine as tick eaters, they free range the whole property, don't quarrel with the other birds, whether turkeys or chickens, some lay in my coop, some don't. Mine yell and run for the chicken yard if something starts to happen or fly into either the goat or the main yard for protection. Or up on the house, where they run around like talkative thunder til things calm down. They alert the pyrs and the other birds and we have lost fewer overall since getting them. I don't have a problem hatching guinea eggs, they pop out like determined quail.
Maybe if they weren't free range they'd be a pain but they sleep in the goat shed, and spread out in the morning. I want to have about 20 or thirty eventually. There are a LOT of deer here and a serious scary ton of erlichia carrying deer ticks. I already had to take anti-biotics once this year for a bullseye rash. And they're already helping with the numbers of ticks and other bugs we're seeing.
