I don't believe it will. You absolutely need a scale. There's no way around it. You can get a nice digital scale from WalMart in the housewares section.
If you want to be successful in incubating the eggs, you need to have the odds on your side.
Start by getting a scale to accurately measure the right water/incubation medium ratio. Remember the scale can also be used throughout the leos life as you track it from neo to adult to monitor its weight gain/loss.
A very good scale will run you less then $50. Ask around this forum to see where the best deal can be found at for a scale. I got mine for $45 delivered.
I use THIS scale and I love it dearly. The best part is that it's only $26.00. May want to pick that sucker up.
That looks like an amazing deal!
Does it come with a bowl? And the setting to still show the Leo's weight with the bowl also on the scale?
What is the shipping on it?
Thanks,
Hayden
