My chickens are now 14 weeks old, and my guineas are almost 6 weeks old. I have been keeping the guineas in a cage in the coop (to keep them separate from the chickens) for a week or so. The chickens free-range during the day and the guineas have the coop/run to themselves. I am wondering when I should be able to put them all in the coop together. The guineas are still a bit smaller than the biggest chickens.
