A few years ago I was looking for some Brown Leghorns and Rural King had a tub marked Brown Leghorns so I bought them. They turned out to be Partridge Rock pullets. I sold them. I did eventually find a breeder and got my Brown Leghorns. They will fill out as they have a lot of growing to do. Many years ago I raised Buff Orpingtons for our local 4-H and FFA. If you have any groups they may want them. I sold a RIR cockerel to a young girl who showed him at a show and he won champion in the youths. Another time I sold another young girl a BO cockerel which she showed and she also placed well with him. You may find someone who would like them. I do agree they look like Black Australorps to me too.
