I have 3 10 week old guineas and 2 8 week old chickens (1 hen, 1 rooster) that are free range on about 2 1/2 acres. I also have 10 chicks (8 quineas, 2 chickens) in the brooder. I will be keeping one or both chickens (if they are hens) and 3-4 of the guineas. My question is, do I need to do anything special to introduce the two groups when they move outside? I was planning to move them to an outside cage for a couple weeks and then just let them out a couple at a time. Will they join up with the older ones?
