I have a chick that is currently 4 weeks old, she was born on September 5th, every one last night the 10 that I have were all acting fine and running around there huge tote like normal, today I went down to change there water and feed out, and noticed one of the chickens sitting there with her head under her belly, she is able to lift it as normal to eat and drink but then currently resumes laying down in said position. I had a duck years ago with wry neck but she was never able to her hold her normal, so to me it doesn't seem like wry neck, could this be a mineral problem, they are currently are on Purina starter feed.
Also should I completely separate her from the rest of her hatchlings or put a few more in with her?
