I've been having a look at the Zooplus dwarf mix funny enough Wobbles
I like it because it has a great mix of seeds, some not seen in other commercial mixes here is the ingredient list:
Extruded corn flour, yellow millet, red millet, corn, oats, wheat, linseed, rice 4.8%, peanuts, wheat flakes, mung beans, popped wheat, canary seed, dari seed, shrimps 2%, chicken, beef, cheese, fish
So the heart shaped biscuits are made of the corn flour & it's where the vitamins & minerals are added.
I am not so keen on the Syrian mix as there looks to be lots of wheat here are the ingredients list:
Extruded corn flour, wheat, corn, oats, red millet, yellow millet, popped wheat, dari seed, carrots, canary seed 3%, buckwheat, sorghum, mung beans, chicken, beef, shrimps 1%, cheese, fish
The ingredients are less varied.
I also like the bird germinating mix which you can feed as it is without soaking it, it has a good mix of seeds
Millet & Seeds and Other Bird Food Supplements at zooplus: JR Birds Germinating Seed Feed for Budgies
Some people feed Trill as treat seeds you could feed this mix like that, just as a natural treat. Would also be good for your new HM
So yes you can feed a mix of all or any of the ones you have said Wobbles
Oh don't forget Petsupermarket has free P&P for the HH & Burgess
