I have some packing peanut roos that came with a batch of guineas I ordered during the summer. They were raised together with the guineas and hang around together. We are slowly eating roos one at a time but there is a particularly lovely one that I had thought about keeping. My son came in the other day and told me one of the packing peanut roos had been chasing one of the guinea hens and one of the guinea roos was chasing the packing peanut. I got to thinking about it and it hadnt occurred to me before that Id never seen any of those packing peanut roos trying to do breed any of the hens. Is it possible that they think they are guineas?
