Good Morning!!!
I loved the wigglers, they were fun, but they were wet and slimy. I had to keep them outside, make sure they were moist enough, they didn't like sun, I wanted them for the poop, not the worm, and the worms had baby worms. The mealworms are in a dry medium, that can't get wet - they get their moisture from food. I can keep them inside - they don't climb or jump. The worms pupate, turn into darkling beetles that lay eggs. I can sift them with different sized screens. It just seems cleaner and more interesting.
Yes, the lighter one is a splash. Not sure about the different faces. Contrats on a great hatch. I had 1 unhatched egg. I turned down the humidity, took out all the chicks, but didn't turn off the bator. 24 hours later I had a shrinkwrapped zipping chick, that I helped out. So, I'd say let it go a little longer?
I do have a basement, but they are going to start out in my bathroom, but it might change depending on allergies.....
I'll be using a tower system...
