Hi, there! I have had chickens all my life, and I currently have 40-something hens and 4 roosters. I'm thinking of getting a guinea or two, because I heard they are good with deterring possums and coons. I'd love to hear your testimonials about guineas (good and bad, please), if/how they actually protect the coop, if they do well with hens and roosters, etc. Again, I welcome good and bad guinea stories.
