I should be getting my first rack in the next few weeks. I ordered an economy plastics adult BP rack from Animal Plastics about 5 weeks ago. Anywho, my question is: Do I need hides while using said rack system? I've noticed the 41qt tubs get kinds cramped with hides in them and I've seen quite a few videos on youtube where breeders are not using hides in their rack system. I'd like to NOT use them but if it is best, so be it. Thanks in advance for any insight!
