Well, yesterday when I saw, it was bleeding a bit. Like, there was some blood on the feather and no feathers on the right leg. Then I witnessed other chicks trying to eat up his feathers and the leg part and I separated it. Kept it alone and in a bit warm area. It almost survived 16-18 hours before dying. It was okay in the morning, but strange in night. The chick was getting weak, and wasn't eating anything or drinking. Kept getting low and in the end it just hit the ground but still take breaths. I just covered it in the cotton, and kept at a side while I am grief. That chick seems dead, only just small breaths.

:/ What could be the reason? The injury caused by other Chick Baby's, right?
