My order of 30 Barred Rock chicks arrived this morning. I purchased them from Schlecht Hatchery in Iowa. All of them arrived alive including the 3 extras. One of the Barred's is having trouble walking on its feet orrectly. It is basically walking on the whole leg. At this point I have it separate from the others so it doesn't get all walked over. Is it just younger or is it stressed from shipping? It likes if I hold it against me. I have it covered with a rag and my hand and it is content. What can I do to help it along?
