Hides in racks needed?

One hide in the back of the tub IF I even use one at all.
I don't have any problems either way.
Also if they don't like it in the back of the tub they will move it on their own.

I don't bother with hides in my racks, if a snake seems real skitish and won't eat, I crumple up a few balls of newspaper and they often use those as hides.

Most of my BPs do not have any hides (I use enclosed racks). I do have a couple of RBI hides, which I only ever use for particularly insecure snakes or when I'm transitioning one into a bigger tub.

Here are the exceptions:

• A fickle, insecure pied that I only know is alive by the flattened aspen because I never see her (she's also the only one on substrate and not a liner... high maintenance, but I love her). She has one hide at the back of the 32qt tub and a large water bowl.
• A ~450g female who got bumped from the hatchling rack to a 32qt tub. She has two smaller hides in there for now, but will only have one when she reaches the next hide size.
• A just-over-1000g female who got bumped from a 32qt tub into a 41qt to make room for the smaller female above. (I wonder if I can convince my SO to let me get a 16qt rack....)
• Two hatchlings who refused to eat a couple times. All of the hatchlings have 8oz deli cup water dishes to help them feel snug; these two also have upside-down 8oz deli cups with doorways cut into the side that function as their hides.
