Hi all. We picked up three RIRs about a week ago. They were straight run and I am hoping at least one of them is a pullet. I am concerned at least one might be a roo. Thoughts? Also, I am thinking these might be something other than RIRs since we have had them in the past and the coloring was nothing like these (hopefully) girls. In the pictures, there is one that is mostly golden, a dark one and one that is redder around the neck and dark down the back.
