Well that explains something about a guinea we have. He apparently has superior genes because he is our lone survivor and has been going solo for 7-8 months. Before his wife and children were all murdered by some nefarious creature he was content to eat bugs in the yard and hang out by the barn.
After their demise he started roosting on the basketball goal and pooping on the driveway. That was annoying but tolerable. I came out one morning to find gray feathers all over the yard and figured he was a goner too. To my surprise, he had simply retreated to some safe spot in the woods to heal his wounds and reappeared a couple weeks later.
Now, the poor fella wants to hang out with people because he has no feathered companions. He sits on the back porch and looks in window all the time. He stays pretty close to us but not close enough for us to catch him and "re-home" him. I am tired of him pooping on everything on the patio but I respect his knack for survival too much to shoot him. I don't what I'm going to do but something has to be done.
My advice would be to replenish his flock (but you will have keep them separated until the babies are half or more grown or he will kill them) or shoot him. Harsh (or a pain in the ass), I know, but that is just the long and short of it.
How's Bella doing?
