How on earth do you get them to not shake their heads around when giving them syringe feedings ! I would rather give my horses syringe feedings than the chickens haha!Try installing her in a pet crate on a couple layers of old towels. Dampen the top towel a little bit, then slip a heating pad on a low setting under the top layer of material. This will generate moist heat which will help. Place the crate in a cool, quiet, dimly lit place.
Be sure to supply plenty of water so she doesn't get dehydrated. If she has not been drinking enough water, she may already be dehydrated, and it's adding to her woes. You might need to tube water into her if you are okay with doing that. If not, syringe the water into her like this. Add a little sugar to it to elevate her glucose.
