I've done a quick search on it and all I can see is that they would interact with calcium carbonate (which is what your chicken needs) so I would be hesitant !?!
If you don't have any other form of calcium for her I would blitz an egg, including the shell, in a blender and scramble that for her.
Hopefully others will give more clarity on Airborne.
