I need some help on my two week old chicks that aren't standing anymore! They were ok until today and now several (7 out of 15) are barely moving on their legs - more like a still shuffle on their honches. They were placed in a brooder with four week old chicks four days ago and were fine as well the older chicks don't have this affliction. I've moved the two week old chicks out to a separate box and even did some taping to their feet, thinking they had curled toes or something! HELP ... I'm a true novice and really thought I had done my reading and research.
