I recently picked up a baby chick from a lady i knew who no longer wanted it. The chick has been kept in a fish tank and fed only crackers. Now it is VERY thin and not at proper stature of a chick its age should be. It also seems very stressed. And its poop is a mostly water, pellet like substance. Any ideas on how to make it better or gain weight faster?? And how to firm its poo up faster??
