I had some eggs in a 6 gram bottle and bought another just in case. I didn't even finish the first bottle and the axies are on beyond eating them now.
The process I used is:
I used a 20 ounce soda bottle with a constant stream of air running through it and set close enough to a 40 watt incandescent light bulb to keep the temperature above 80 F.
I mixed an eighth of a teaspoon of eggs in a liter of aged water with a tablespoon of non iodized salt. I set this up every other day and had more shrimps than I knew what to do with. I was feeding 18 larvae, btw. It was easy, in my opinion.
I fed the axies twice a day. Each of the axies was housed in its own container. The first container held about 200 mL of water and the next size up held about 1 liter (Glad storage container). This keeps the tiny larvae close to the even tinier nauplii (newly hatched shrimps)
I changed the water every couple of days to keep the water clean.
Since you've got so many eggs, keep them in the refrigerator and they'll last a long time.
. Thanks for the advice, It was very helpful.
