You can make large pots of broth and store portions in the freezer. Then take a portion out, warm it up and add to it whatever herbs you are using, you can also then add her food (you could have semi-raw food added, which would perhaps be easier right now.)
A useful addition to the bone broth would be a little seaweed - for added minerals.
