The girls are about 10 weeks old. I bought them at Big R which I think is a Big M(istake). They didn't have them by breed but here in Colorado Springs I didn't have a lot of choice so I rolled the dice and now I have no idea what these two are. I was hoping for Australorps and maybe Orpingtons or a Barred Rock. The black ones looked like they may have been Rocks at a day old but obviously I was wrong. The other looked like it was possibly an Orpington but wrong again. I have looked at a couple of books but am stumped. I have 2 of each of these and a few Americanas. Hoping for good layers at least.
