2 Dead

[Kayana]

I bought 3 bantams and 3 mystery chicks from TSC and so far one bantam died, one is dying I think. She keeps screaming and wont stop til I pick her up and hold her in my hands. She is acting funny not playing with the others and its just continuous cheeping (loudly). I don't know what to do, and its breaking my heart these little babies are dying. Should I quarantine her and see what happens? My husband of course does not care and has this "this happens sometimes" attitude. She just keeps screaming and idk what to do with her. Her poopie does not seem odd in any way. help
