We had guineas when we first moved to the our property. We bought them a few days old. Raised them in a 10 by 10 for 6 months so the would remember where home is. After 6 months I started to let them free-range. They did great for about 4 months then started getting picked off by a fox because some times they would want to sleep some where else besides there 10 by 10. But your right there loud and when your around them long enough you can tell there different sounds and what they could mean.
