I've been raising 9 ducklings. Well 2 weeks ago one of the ducklings just abruptly stopped walking.It was perfectly fine one day and the next it couldn't stand. It couldn't bend its foot straight and it would crawl.Ever since then I've looked all over the internet and can't find a solution. I bought niacin pills and added it to the water. It didn't really do anything. It did get better and now it can almost stand. What worries me now is that its walking with one of its foot twisted to the side towards belly. he is standing with his foot to the side. He still can't put his legs straight up and I'm worried about him. Can anyone give some advice in this topic. I want whats best for this duckling and i hope one of you can help me. I've tried to help him and i don't know what else to do.
