So I'm hatching my first ducks, from my Peking in my backyard. I've read up on everything and I now have a hatched duckling sitting in a brooder. However, it seems like one of its legs are not working at all. Is this common? I was nervous about this duck from the beginning as we put it into our friends homemade incubator, which didn't keep a very constant temp or humidity. I went out and bought one online with good reviews and it seems to be working well. We have 4 more eggs due in a week or so. Anyhow, back to the little guy we currently have. He struggled breaking out of his egg and I gave him a little help. But now I'm thinking he struggled because his leg wasn't working. It doesn't looked deformed or injured, just limp. Any help?
