My chick is 2.5 weeks old. It was running so fast and flying up stairs. It could climb up to my shoulders too. One day it can't stand up anymore. It may have accidentally got crushed underneath a heavy parcel when I was not around. I tried to stand it up but it merely collapsed. Is it paralysed forever? It's still eating, drinking well and chirping as usual. I have to handfeed. What should i do?
