I have 3 Lb hens that are 9 months old and a roo that is about 16 weeks old. Id like them to be together. He is in a different pen Since hes a roo can i just put him in or should there be some getting -to- know- you time with him seperated from them for a week just where they see each other? OR can he be out free ranging with them an hour or so and then go in with them that night ? Should he be older? He doesnt crow yet Their coop is small. Thanks ahead.
