I noticed the other day that one of my 4 chicks seemed to have trouble walking, but nothing really bad, just fell over occasionally. However the next day it's condition had worsened. The poor thing could hardly stand let alone walk, although it tried with little affect, only making its legs splay out as though doing the splits. I've looked it over for injuries, but appears fine, no swelling or cuts. I've no idea how it happen. Little Bub, is still eating and drinking but is constantly tiered due to the effort it puts in trying to walk. I thought at first it was saddle legs, but it doesn't seem to fit it quite right. I've separated her from the others so she doesn't get trodden on, and she spends most of the day asleep or eating inside with me.
Additionally I have constructed, a type of sling to help her stand it the correct position, hopping it'll help strengthen and correct her legs.
What more can I do to help her?
