It's best to isolate her away from the flock so she wont get excited nor get other birds in an uproar. Your hen should be caged until she heals. Ensure you provide feed and water while she's caged and keep the cage as clean as you can.I set up a dog crate within run. Is this ok? Also, should she stay in it overnight? Also, what if she starts acting super stressed while in cage in the run?
