Baby chicks keep dyeing for no apparent reason.

[Hazel feather]

So I hatched out one chick out of shipped eggs . She was lonely and I bought her five other chicks to keep her company . This was Saturday 7 February . On Thursday , one chick died . Stretched out , neck extended and legs stretched out . On Friday , two more died . They were in a big area , lots of food and fresh water so I decided to make the area smaller because it seemed as if they were out from under the brooder too long and then went back under and died . Two more died after I made the area smaller . One side of the brooder ( it’s a heat plate ) is higher so they can move around if they get too hot. The last one is continuously crying . There were no symptoms of any disease/ sickness . Anyone have any idea what caused this?

Thanks in advance.

Could you post a photo of the area they're in, and of the chicks themselves (the survivor and/or any pics you took before the others died)? You say they didn't appear sick but how were they behaving, generally, before they died? Any chance they could've been exposed to some kind of environmental toxin - mouldy food or bedding, fumes from vehicle exhausts or non-stick cookware if the brooder is in a garage or kitchen, any other chemicals..?

Are you monitoring the temperature i. the brooder with a thermometer?
