I got 20 Cayuga duck eggs about a mouth ago to hatch out for an FFA project. They were supposed to hatch March 10 and none of them did. After candling them I found that there was only one more alive and it had already broken into the air sac. So I helped it and happy to say that the little guy is doing fine. But I'm really concerned as he won't stand up normally and moves funny. His legs are staying weirdly positioned as you can see in the pictures. How can I help him??
