I do not have guineas yet, but would like to get some. My neighbor does have a flock of guineas. His guineas visit my yard on a regular basis. Is there any way other than full time confinement to keep my guineas from becoming his guineas? I would hate to buy them, get attached and then have them integrate themselves into his flock. He may not want that to happen either!
I don't have guineas but my best guess is, to get them a pen of some kind and keep them in it for several months. If they are like chickens they will go there to sleep each night after they are allowed to free range. They will also bond together.
I wish you lived next to me. My neighbor has these birds ( would give you all you want).
Glad to see you wont to keep them home. The ones next to me are always loose roming my yard and garded and making a mess on my sidewalk. I like animals had have several chickens, rabbits, and birds myself. But would never think of letting any of them visit my neighbors yard and garden.
One of my neighbors also had roaming guineas that used to come share breakfast with our horses. Almost every morning there seemed to be one fewer, now there are none so roaming the countryside didn't work out too well for them...
