I have a chance of getting some 4 month old guineas, I would like to know how long they would need to be confined to learn this is their home? I have 10 guineas that are about 8 months old, and they have been free for a couple months. They were confined for two months. They were ten weeks old when I got them. I really would like to have about five more guineas, and just saw some on craigslist today. But don't want to get them without knowing how long it would take them to learn this is home.
