My chickens and guineas have lived together for years without problem. Once in a while you can end up with an aggressive guinea towards the chickens. That one should be removed from the flock. But most of the time they will get along just fine with each other. They will go their separate way thru the day but they all sleep together in the same coop at night.
Guineas are happiest in flocks. The recommended number is at least 5 or 6. If you have the room and no aggression problems, I would advise keeping all of them. The whites and lavenders should make a very pretty flock.
Thank you for the advice. I will see how they all get along together. I still want to eat one though
You will be pleased! We raise them for dual purpose, they are awesome table birds.
