I have had guineas, turkeys, ducks, geese, & chickens sharing space for many years. I have to admit they have lots of space to roam many acres so that of course helps. Various birds have disagreements from time to time. Sometimes it is a turkey and rooster, sometimes a hen & hen, sometimes it may be a guinea and a turkey hen. These disagreement are generally short lived and mostly no blood drawn.
I did have a guinea male try to take on a turkey tom a few years ago. The tom grabbed the guinea as they would generally grab another turkey tom and shook the guinea thus breaking the guinea's neck and killing it. This was a one time occurance in several years.
Anyway, the guineas generally stay to their own kind as do the other birds, however they do share the coops with each other. I do believe it helps to have the guinea keets grow up with chicks since everyone gets used to seeing all the other various birds and they grow up thinking it is normal.
Hoping you have a successful co-existance.
