Ours free ranged but unfortunatley not far enough.Can't argue with that. The guineas I had yelled at each other pretty much all day. I find it endearing though. Maybe cause I have a very loud stereo system, and very good headphones lol.
I have to be honest and state that they were a lot of trouble for not a lot of joy and the Goshawks seemed to like them.
A further problem was while it is true they foraged well they are direct competition for the same type of forage as the chickens. If you free range chickens this might be a consideration.
They got moved on and are on my never try that again list.
