We got a chick 6 days ago from my daughter's school. It is approximately 3 weeks old. It was born with a deformed leg, but seemed to be adjusting well. It started having seizure like symptoms this evening. It will stick it's neck out kind of turn it slightly and shake uncontrollably. It lasts just a few seconds, but is happening about every 5 minutes. Please help as we do not know what to do!!!!!
