What kind of advice are you looking for? I say go for it. You won't know what the BB's will look like until you produce them right? Besides hitting on BB's you will also get pastels, spiders & normals. (depending on the clutch size and your luck) No guess work! So... my advice to you is to get that female spider & do what has to be done whether you have to raise it up if it's a hatchling or whatever! Do what will make you happy!!! Good luck to you...
