My baby chicken keep dying one bye one

[MINDANAO DAVE]

An the one I found last night was very disoriented An could not hold her head up An had pasty on her but had enough energy to chirp but nothing else she finally payed to rest about 10 this morning seem what ever it is it a painful 10 or deaf please help me figure out what's going on

If she had a pasty butt that may be your problem. Change your feed might help.
