I bought six chickens to start my flock, and I'm sure that 3 are production RIR, 2 are possibly Red Sex-links, and the last was described as a RIR and Brown Leghorn mix. I got them on 10/20, and moved them in that evening. They seem to have taken to their new environment rather quickly. If anyone can confirm or deny the identity of these birds, I would very much appreciate it. Here's a picture of their new home (5'x8' coop, 8'x16' run), and a video of the girls... Sorry... I was thinking about the picture when I named the video. DOH!!!
