i have a just under 6 foot boa that was raised by someone else with no hide and he has no issues whats so ever. I do not supply him with a hide but do supply him with shredded paper to go under if he indeed feels insecure but i have not had any problems with him since i took it in as a rescue. He eats fine,sheds fine,and can be handled with no problem. If you have a very flighty baby then i would personally supply a hide but imo its not needed.
