Egg sac

[Napier19]

Caught a couple spiders hanging around my house to add to my T collection. They seem to be doing good. Have eaten and webbed up some. Today I seen what I presume is the female sitting on an egg sac. I found very limited info online and just curious if someone can provide enough info to rear the young up to be big mature spiders. I removed the sac put in in a deli cup with moist substrate temps in mid 80s.
