I'm not sure how close she is... I do know that they get squarer stomaches as they get closer. You could put her in there or not, it's up to you... if you do, make sure there are lots of plants (real or fake) in there for the babies to hide in so she can't eat them. You'll probably get some to survive even without the breeder, and then you don't have to stress her out by chasing and netting her.
