This morning I noticed one of baby ducks was holding its head crooked. She can stretch it out, but keeps it crooked, I seen her drink fine, but the way she is holding her head is weird. I haven't seen anyone attack each other, she doesn't cry when I touch her neck, so I don't think it hurts her. Can anyone tell me what's wrong with her and can I help her? I don't know for sure if she is a she. She the one in front of first two photos, and in the back on the last photo. Only the last really shows what I'm talking about.
