Travis are guinea fowl friendly and do they swim on the water, thus shedding feathers in the water?
Are these creatures able to live in a coyote area? We have seen 3 at a time in the past.
My experience is based on a few friends who have guineas. Guineas are smart birds from what I have seen and have to be raised from chicks to get them to stay on your land. If you get them at an older age, they tend to wander far and may never come back. However, they are very friendly to their owners and people they frequently see. However, they are quick to make alarm calls and go nuts when they see things out of place. A reason my friends like them or hate them, depending on how often they get to making their alarm calls... They are land birds and do not swim in water.
As far as coyotes, my friends(3 of them) who have them all live in areas with coyotes. They've been able to maintain flocks for several years now. I know they loose birds here and there to hawks, owls, foxes, bobcats and I am sure coyotes. However, it's not overly often. They loose far more chickens than guineas. If you can train your guineas to roost in an elevated location it's a big help in lowering predation.
