Once they are 3 weeks old I'm going to take over raising them. I'm thinking what I'll do is move them into a sperate cage from the parents and put a nesting box in there with lots of warm materials. Then as a cheaper alternative heating source I've seen a hermit crab heat matt in my local pet store, it doesn't say how warm it gets but apparently they are kept at similar temperatures.
The challenge is that I'll have exactly one week after taking over until I go to tafe from 7am to 4pm during the week.
I need to know how much I need to feed them and if I can leave them for 9 hours a day. Maybe if I get up at 5am for a feed then another one before i leave and then another one when I get home. And leaving the formula for them during the day to eat along with a bowl of seeds so that they might become weaned.
Hopefully someone with the right knowledge can help me on this one

Thanks!
