Good afternoon everyone !! I've done a lot of research on what to use for dust bathing, but not much of the preferred materials are available to me at the moment :/ I do, however, have extra REPTILE SUBSTRATE, which is essentially calcium sand. It's very fine and my sand snakes will bury their whole body and face into it without irritating their sinuses or cause respiratory issues. Do you suppose the sand is ok to use for my chicks to keep practicing their bathing ? They've been going outside for half days but lately it's been close to 100 degrees here Any advice is appreciated !!
