People who did not grow up with some baboon spiders in the back yard tend to "love them to death".
Hogwash.
Is your dog still alive? If so, you grew up with a pack of wolves on your lawn?
Caring for spiders takes 10% knowledge and 90% common sense. If you don't want or can't care for 1200 slings, the solution is easy, keep the male away from the female. If you MUST breed to "gain experience", give the slings away.
