My broiler chicks

[Mariyam Abbas]

I BOUGHT 6 BROILER CHICKS ON 28TH MAY, 2018 NEARLY 10 DAYS OLD. LAST WEEK ONE GOT BRUISED ON LEFT FEET AND BECAME DULL. WE TREATED IT AND UT WAS FINE RUNNING AROUND BUT 2 DAYS BEFORE WE FOUND IT DEAD IN ITS CAGE! WE STILL DON'T KNOW THE REASON. TODAY IN MORNING WE FOUND ONE OF THE 5 REMAINING CHICKS SLEEPING A LOT, IT RAN FOR FOOD BUT WAS SO SLEEPING THAT COULDN'T TAKE THAT IT. BY EVENING WE GAVE IT TETRACYCLIN 500 MG AND FEW MINS AGO IT STARTED ROLLING, JERKING, SPILLING WATER AND DIED I DON'T UNDERSTAND WHAT IS HAPPENING TO THEM.

I AM NEW TO CHICK RAISING PLEASE HELP ME HOW TO KEEP MY REMAING 4 SAVE?

Do they have heat?
Any other symptoms like swelling of the eyes, joints, mucous, sneezing, etc.?
A photo of where you are keeping the chicks along with what the poop looks like would be good.

Coccidiosis is the first thing that comes to mind. Treatment is with Amprolium or sulfa medications. Do you have access to either one of those?
