Just chiming in to say that Shrimp's doing very well! She's still not smart enough to get out of the rain, but her head is upright, and I haven't seen her twist it in weeks! Most of the time, I can't tell between her and my other barred rock. She was even accepted by the rest of the flock and free ranges most days, with her BFF LaLa. Her legs are still white, but her comb is plumper and red most of the time (it sometimes seems that it's even grown a little!) and the past few days her eggs are starting to darken! We kept her on the vitamins for about four weeks and she now gets nutri drench in her waterer about once a week. Thanks for all of your advice!
