and all seemed fine. Temperature in brooder is 97. I did the sugar water for the first eight hours and then switched to regular water with minerals and electrolytes and they all seemed fine last night... woke up this morning with 4 chicks in a bad way. 1 is almost dead, 1 is lethargic and 2 act like they don't have any energy to stand let alone eat.. any ideas as to what is going on?? they received maerks (sp?) vaccine from the hatchery.
