Darla gets a teaspoon of seed mix every evening, and Annie gets a table spoon at the same time. Plus a treat (or two or three for Annie if she is looking cute) every other day or so, something like a mealworm, yoghurt drop, dried fruit, peanut, biscuity thing, herbs, or a bit of veg (Darla isn't a fan of veg but Annie seems to eat anything
)
ETA: I feed Silver's mixes, basic dwarf for Darla, basic Syrian for Annie, and it all gets eaten -- the food store that gets cleaned out qeekly is made up of all the ingredients of the mix
