If you have a syringe drawl up a mix of 1/2 water to half poultry vitamin. Inject about 2-3 cc under loose skin where neck and back meet. This will help get something in her. If you can find a large syringe with a pencil eraser wide tip or a little smaller (60 mm), and some soft flexable clear tubing you can try and tube feed her. Buy baby parrot feeding formula(Exact) or take very finely ground chick starter or pheasant grower and mix with a lot of water and vitamins. Fill type with the wet mash. Put a tube about 8 inches long on the end of a syringe. Open the chickens mouth, you will see a hole right behind it's tongue.......... STAY AWAY FROM THAT HOLE that goes to the lungs. The bigger hole behind that is the throat that leads to the crop. Use a flash light if needed and hold tongue and bottom beak with thumb and pointy finger. You may need someone else to hold bird in a towel. Insert tube down that hole, it should slip easy in and down, you will see tube push on skin and follow it down to croup. When it looks like you are in the croup, push the mash in from the syringe. Pull tube out quickly when done.
