Always keep an eye out for Coccidiosis,if you are not familiar with the symptoms or are new to keeping chickens look up information,cocci kills very fast and is the leading cause of death in chicks.Thank you all for the advice, I will keep you posted on her progress, whichever way it may go. She hung out in the recliner with me tonight for a while, wrapped in a towel all warm and snug. Her crop still full compared to some of the others. I offered her more egg yolk, which she ate quickly, almost aggressively. She then napped, but had some head shaking, beak smacking episodes along with one or two times sort of big open mouth yawning. I took her back down with the others, where she was quickly welcomed back. I guess they like to snuggle with her too!
It did cross my mind that she may be a bantam or some other small breed since McMurray includes a "free exotic chick" with their orders. I went for a surprise standard rainbow layer package so aside from the obvious 5 EE'ers, Silver Spangled Hamburg Trio, and Silver Laced Wyandotte, the rest of the yellows and chipmunk looking chicks are a mystery.
Thanks again!!
