I prefer Kaytee hand feeding formula. I buy a 25 lb bag and keep it in the deep freezer so it won't go bad. I don't think many pet shops keep this size bag in stock, I buy from a large feed store. You might be able to have your local pet shop put in a special order for you.
I soak my feeding equipment in Nolvasan.
This will eventually "eat" the rubber on syringes.

Some breeders weigh there chicks at every feeding. I just bought a digital postal scale for this. I glued a receptor so I could put a small T stand on the scale to weigh my "larger" birds (Jardines to Moustaches).
