Please help! Small chick wont move or stand! Several others already dead

[Mahamaya]

The past two days two other chicks have died. They seem to have low energy at first before they just lay down and stop moving. I tried feeding them sugar water and egg white thinking that they might have low energy. Once i did that they seemed to regain some movement before they just drop dead.

Now another one is sick since this morning. It and several chicks seem to be sneezing so I got them pills but idk whats wrong.

Ive checked for any injuries or other symptoms. The one sick chick only seems to have runny poop, nothing else is out of the ordinary

I give the chicks dry (medicated) fodder. Their water i change every few hours since they keep getting it dirty. The temperature where i live is high so I have them in a room with several windows and water cooled fans cooling the room. The first few chicks i got died shortly after i got them as they were in poor health. Several of them are colored ( the easter egg chicks) as where I live they dont have regulations for that.

So could anyone please help me? I dont want to loose another chick ;-;
