I came home to discover, much to my shock, that my pre-molt E. pulcherimaklassi female, which I have had since May of 2010, has dropped a big sac!!  Not pre-molt at all, it turns out.

Is it common for a tarantula to remain gravid for almost two years?!?  It had never molted, so I was a little suspicious.

And now that I have a sac, this is my first; anyone want to give some simple early advice before I delve deep into research?  I'm really hoping to get some babies out of this and spread them around, as I've yet to encounter them captive bred.

not common but it is possible

tarantulas use deferred reproduction, so the sperm cells are quiescent until the female makes an eggsac and mixes the sperm with the eggs and an activator chemical for the sperm

as long as she hasn't molted since she mated at least some of the eggs could be viable

Definitely hasn't molted in my care, and I was told it was wild-caught when I bought it.  How long should I wait before pulling the sac out and, I assume, shining light through it to look for yellow eggs?

Mom has been sitting on the sac for 24 hours straight.  Pretty amazing to watch...

Make sure to get the water dish out of the enclosure before she drags the sack thru it. You don't want any water touching the sack or it'll get ruined. Keep it incubating @ 80F or so. I usually pull mine at 40days after drop.

Uh oh.  Pulled the aforementioned sac, and I have a feeling there's a problem.  I've never done this before, but most of the eggs sure look shriveled and dried out to me.  Anyone have comments?  Might I get a FEW babies out of this, maybe..?

Bummer...from what I can see in the pic most of the eggs looked dried up and or bad. looks as though the humidity was too low. At thirty days you should be seeing EWL's .  

 Did you separate the eggs and find any that still look plump and round ? or with the start of legs..

I think I screwed up.  Humidity was LOW in her cage, because this is a scrubland species which never liked having moisture in there.  Furthermore, I was counseled to not keep a water dish in there (which I had otherwise been doing) out of concern that she would roll the sac into the water.

They're in a presumably-humid incubator now, and I will pull out what seem to be better ones, but honestly, none of them look shiny and round enough to my eyes.

Hey it happens,
Trial and error...I've had a few sacs do the same thing. Did the female burrough in or silk over her hide ? typically they would hide and protect the sac . My females have never moved far from where they drop the sac.
The next best thing would be to just pull it early and artificially incubate the eggs.
Good luck hopfully some eggs will make it...
