Guinea fowl are loud, not as friendly as chickens, not very smart, but for some reason they are fun to have around the farm.
In late summer of 2015 I got a dozen guineas along with some chicks. Over the course of the next few months 4 of the guineas went missing or died. I found one guinea chick dead from what I suspect was heat stroke.
Guineas are not supposed to be good parents, and that may be true. What I am seeing with my guineas, the chicks have to keep up with the flock, kinda like sink or swim. While at the same time the flock protects the chicks.
The guinea flock will run off any chicken that dares get close to the keets. Guineas do not seem to share food with the keets, but rather shows the keets where the food is at. At a week old I saw the flock taking the keets close to 100 yards from the chicken house.
