It's okay,it's my fault for not taking care about my chicks....
And the saddest thing is,the other one escaped just to tell us about it,she is currently tweeting out load because she doesn't what to do...
UPDATE:We have put the chick in it's own box with a jar that has warm water in it,we have also added a towel on top of the cage,all we have to do now is to turn off the lights and check back later.
