Hi, We've been thinking of getting Guineas. We have 20 Buff Orpington chicks that are 1 week and 3 days old. The Guineas, we've been told, are 3 weeks old. We are not sure if we will take one or two and thinking of adding them to the brooder with our chicks. We are hoping they will become a big happy family. Is this possible? Do you think they would harm our chicks or vice versa?
