So my Avicularia Metallica has webbed itself off from the enclosure. This is my first tarantula and I’m pretty sure it’s premolt however as of yesterday it made a thick ball of web that looks like an egg sac. My T hasn’t been bred with another and this is the only one I own. The pet store told me they suspected it was a boy but “the last molt was inconclusive.” Could this be an egg or is there another explanation for this?
