thank you so much guys for all your help, i can say i sure know more now. but the more you know the more qs you have, so..... until now i didn't even know they eat mice in general i don't know what i was thinking but spiders that i saw outside all eat insects, but i guess with big tarantula especially if one named bird eater, would eat that. why are they called bird eaters, are they up to eat a bird?
for a baby i'll have small crickets, i get 2weeks ones for my baby geckos, so that stuff is always around.

a qs regarding mine. you are saying he is happy when he barricaded himself in his burrow. mine are out during a day, sitting on a cork on a ground and then goes back into his burrow at night. what does that mean? hungry? happy? just sitting minding his own business looking around? he was housed in his current tank 2 days ago and didn't dig much yet, may be s/he likes the burrow it has have a pic, will post as soon as i get to a normal device.
is there any explanation to this behavior? curious

oh and when and how to sex them? is it something i can do myself?
