No, keep the shelter spots in there, as for several days after the tarantula molts it will be very soft and easily injured. Make sure there are no live prey items in the terrarium, as at this point they could easily kill your pet, but any type of shelter and hiding spot is actually more critical for the tarantula at this point.
If your looks healthy and with vigor, you shouldn't worry about that. Your chaco spider will molt when it needs to.
I have had a tarantula for several years and have found the larger the animal the older it is. As it molts it grows. Mine is fairly large now and is about 10 years old. This is my third tarantula. I hope you have given it a nice place to hide in its home, have a heated environment with a hot rock or heating element under the cage, and provide water.
A butterfly molts after gaining wings.
If the spider does not have tibial hooks on the first pair of legs, then you need to be looking at the ends of the pedipalps. Males will have bolbous pedipalps where as the females with have pointed ends just like the legs. However you generally cant sex a tarantula whilst it is still and juvi/subadult or spiderling, you need to wait until it molts to its near full size.
Yes! Every bird molts. If it's a bird, it molts.
no not usually
As it molts, it will grow. :)
because it has no protection left.
it molts
After it molts, a crayfish needs some time to grow a new and larger shell. During this time it has no shell to protect it from attack, therefore it hides.
Soft.
No, it regrows them
