I've never seen this before... One of my broody girls has been really lazy about laying on her nest lately. She really only has been doing it when she feels like it. Whenever I go outside she's running around the pen with the other ducks. I checked on all of her eggs a couple days ago by candling them and they were all alive and just about ready to pip. So I checked on them again yesterday and one was pipped and I could feel one moving, but it looked like she hadn't sat on the nest all day. I went out this morning and one baby was hatched, but she wasn't on the nest... One of my other hens has one duckling that's about 1 week old. That baby was sitting in the nest next to the new duckling! It's like the older baby adopted the new baby as its sibling. The other two eggs have small zips started. Should I just leave the new baby and the eggs alone?
