I have a little black silkie named soot. Her head is too small for her body. Every day she gets clumsier. She can't walk. She can't sleep on a roost. Does she have a genetic defect? Does she have Marek's disease (if the name is wrong, sorry. You know the disease that makes chickens paralyzed)? Most important, when do you think she'll die? I don't want her to die, but that's the direction her condition is heading.
