Runt chick warning sad

[Freeloading slacker]

I went to go check in on my chicks and saw my little runt nutmeg on the ground chirping but no voice. She seemed in distress so I took her out. She was having some difficulty walking and holding her head up. I went and held her head up and tried giving her some water, she didn't want any. So I tried figuring out what was wrong with her, checking her over for anything that might be the problem. Then she died in my hands. Does anyone know what the problem is and if it can hurt my other chicks?

She probably too weak to live, was she smaller than the rest of them? She might have gotten picked on or just died of natural causes so sorry for ur loss
