I just received two chicks of unknown age and breed from a friend as a surprise gift. I believe they are buff orpingtons but I'm not sure. I also believe they are around 10 weeks of age but I'm not 100% sure of that either because I've never had buff orpingtons before. Well my questions are: what breed are they? How old do you guys believe they are? And what do you believe is the best way to integrate them with my 4 adult Rhode Island reds and New Hampshire reds? Here is a picture of them.
