I'm happy to hear Dumpling is doing well! I hope he is gaining weight.
I've used coffee grinder to grind herbs. You can probably use food chopper as well - I just never tried using it. It is fine to store ground herbs for a few months in an air tight container or a Ziploc bag (just make sure that the alfalfa hay you are using is dry). For example, you can grind 110g of alfalfa, 20g of various herbs including rose hips, and 40g of rolled oats (probiotics can also be added). Then you can add some Critical Care to the mix.
In general, chins should be fed about 60 ml (dry syringe feed mixed with water) per 500g of body weight daily. However, you need to take into account that your chin eats alfalfa hay and even some pellets.
