This is the current mix our birds are devouring and seems to be the most favoured yet. Should easily last 6 hrs without going bad in their cage though most won't eat it once its sat for too long.
You will need a very large bowl for mixing.
All ingredients fresh as possible and organic-
small butternut pumpkin raw
1 Capsicum raw
2 large chili raw
small broccoli raw
few dandelion leaves raw
4 kale stalks/leaves raw
handful of spinach raw
6 or more baby carrots with greens attached raw
handful of snow peas or green beans raw
fenugreek sprouts raw
1 zuchini raw
little bit of parsley raw
All of the above ingredients are chopped raw into tiny pieces (not mush) with a food processor then added to the mixing bowl.
then add
1 cooked large sweet potato squashed. Microwave until cooked- about 10 mins total, poke holes in it with a fork first.
1 sweet corn cut off kernels with knife and cook them with sweet potato for 3 mins at the end.
add them to mixing bowl and mix thoroughly.
We then made a grain mix using only ingredients with 15 min cooking time and cooked them together. Cold rinse first then use absorbtion method so no nutrients are washed away.
quinoa
millet
short grain white rice (only used this time because it cooks in 15 mins usually use brown)
red lentils
green split peas
let them sit in strainer once cooked to remove excess water then add them to mixing bowl and mix thoroughly.
You can also cook a seperate mix of beans and add them for a more complete protein, but they require a far longer cooking time.
If you are already feeding sprouted beans they aren't required.
I then use a seperate small bowl to premix dry ingredients-
hemp seeds
sesame seeds
buckwheat
purple dulse powder
sea kelp powder
rose hip powder
lemon peel powder
orange peel powder
freeze dried barley grass powder
freeze dried ginger powder
chili flakes
turmeric powder
cayanne pepper powder
add this to mixing bowl in small amounts while mixing to ensure it gets mixed as evenly as possible.
We then spoon 2 days worth into ziplock sandwich bags. Remember to buy a few boxes you will be amazed at how many servings you get out of it. We then put these ziplock bags inside the more expensive "freezergaurd" ziplock bags and then put them in the freezer.
Make sure you feed it daily, and remember to put the next mornings bag in the fridge the afternoon before. If you heat it to defrost it will increase the speed of bacterial growth.
not sure if I've forgotten anything, hope this helps

good luck
