I saw on Craigslist someone in my town listed a single male guinea needing rehomed. Since my flock is down to 5 right now and we have had some recent losses I figured I’ll take him in. However, how to I add him into a free ranging flock. He’s used to free ranging also but if I just let him out in the evening when I throw food out to mine will he stay with my guineas or do I need to confine him for a few days?
