Yes you can use egg yoke from day 1 to day 7 then brine shrimp are by far the best live food until they can be switched to flaked food. If your looking for something easy for hatching brine shrimp go with the "Shrimpery" by san fransico bay company its only like $9-12 in the states and you can order it online for not much money its easy to use and very little clean up and you have brine shrimp 24 hours later, and they will continue to come for another 36 hours after the first batch. hope this helps
Okay. I live in the California mountains and, though its not snowing right now, it was 21 degrees this morning and it might snow. Will the brine shrimp die in the cold? And will they ship to P.O. Boxes?
lol you dont get it the brine shrimp are eggs and you hatch them so no they wont die because of the cold the eggs can take just about anything. The shrimpery is just a hatchery for the brine shrimp it works well. and yes they should ship to a po box
