I'm extremely upset now as the last of my 7 bantam chicks died.I have No idea at all on Why they all suddenly died. I do not have an incubator and my chicks were hatched by it's broody mom. After hatching..by the 3rd day the chicks started dying.they were eating chick feed and drinking properly but suddenly 1 by 1 started falling dead.the last one died on my hands a few minutes ago.it was gasping for air and I'm clueless on Why and What happen? Where I live..I can never get medicated chick feed..only Normal ones..I fed them small mealworms as well..all seemed fine but now..all dead.anyone has any idea why
