Advertisement So I got a surprise the other day where my male Hacklemesh weaver (Callobius spp.), somehow found an old "dud" eggsac and somehow managed to fertilize it. I know I probably sound like a clueless dweeb, so anyone know how he managed to do this? Also any tips for the spiderlings? there's currently snow outside where I live, and I don't know anyone who would want them. PLEASE HELP!
