My cheap grit mix
Posted: Sat Dec 13, 2008 1:15 am
Made up a batch today approx 1 kg.
One third crushed cuttlefish bone
one third baked eggshell
one third charcoal
Method.All ingredients are crushed to the desired size in a very large old saucepan,one item at a time,with the head from a sledge hammer.
start say with the cuttlefish crushing a bit then sieving to the desired size.until the required amount is crushed.(I collect the cuttlefish myself from the beach.And hang in the sun in a onion bag to dry and sterilise until use)
then the charcoal which if possible make yourself in the backyard.I burn tree branches i have pruned around the place or firewood.check out info on what you are burning as treated timber is poisonous.and i would imagine some trees in countries could contain toxins.use paper to ignite your charcoal not petrol etc.and then do the same with your cold charcoal as with the cuttlefish.Save a few larger bits to put in the aviary as some finches use it to line there nests,namely emblemas and pictorellas.
Then next is the eggshell.i bake mine in the convection oven for 20 mins on a high temp and store until ready to use.Same again crush and sieve to desired size.
once all of the ingredients are ready mix them up.If you want add a little mineral.I put in a sprinkle of bio cal.and then add to aviary in small coup cups or receptacles.
Note.if you want go quarters with a shell grit in the recipe.
This time i have saved some fine powdered cuttle bone as some of you guys sprinkle it on sprouts so i will try that.crushing with the hammer is quite effective.
