I have a flock of 5 birds that free range during the day and fly into the coop at night. Barred rock rooster 8-9 weeks old Buff orpington hen(i believe) 8-9 weeks old 3 guineas (2 white 1 pearl) 10-11 weeks old These 5 were all raised together I currently have 10 chicks in the brooder. 8 guineas and 2 chickens. I want to keep 3 of the guineas (1 lavender, 1 pearl with white and 1 lavender with white) and one or both chickens (if they are hens). How do I introduce them to the existing flock? The rooster is already very protective of the flock. Also the neighbors have 3 chickens (1 rooster and 2 hens) that free range and they come in our yard sometimes. Will the two roosters fight? And when will my rooster start to crow? He still cheeps.
