Just hatched pekin with swollen legs, yolk not absorbed and wry neck

[Mandarin28]

I just "rescued" 3 ducks that hatched this morning. All 3 pekin. One i have narrowed down to have wry neck and am treating with nutridrench. He already seems to be doing better.

The 2nd duck has two swollen legs and I want to say a splayed foot. I will attach pictures. I'm not sure how to help him or if there's anything I can do for him. Should I cull him?

The 3rd has not fully absorbed his yolk but the person didn't know what to do so they took it from the incubator and it had been under a light so shaving are now stuck to what is left of the yolk. I have read to use a warm rag to help it soak it up.

Please give me any advice possible for these guys.

By now it's probably too late, but sometimes you can bandage their legs straight using tape. I'd be concerned about infection in the one with an unabsorbed yolk; not sure if you can do anything for that other than apply antibacterial ointment and keep the area as clean as possible.
