I guess it is possible. They were sold to my brother in law as "Chocolate Sebrights". I knew that they were not Sebrights because the rooster was not "hen feathered" and they have a single comb and the type did not seem consistant with Sebrights. I have Golden and Silver Sebrights also and know that they did not look like them. When I was researching to find out what they were, I posted pics on different forums and they concluded they were Serama so that is what I went with. I know that the plumage color on the Serama did not breed true abd there were hundreds of different colors but I did not know that the leg color was consistant. I learn something new every day! Thanks!
