what i think happened is that there wasnt enough room in that small container for your spider to molt so when it did molt the leg broke because as it was pushed out of the old skin up against the wall it bent and broke.
It should re grow the leg back durng the next few molts. and its not really crippled unless this happened to all the legs.
i can't see the pic while i am at work, but i do want to comment on the "the container looks too crowded or too narrow for it"
tarantulas, and spiders in general seem to need only a tiny amount of room to molt successfully. i have had tarantulas molt while they were being shipped to me and they were fine. i keep a lot of my spiders in "too small" of space according to a lot of people and i hhave less trouble than most with molts and what not, it seems. i have never had a spider get messed up from molting in a small space. i have had scorpions die from trying to molt while in shipment... and seen scorps get deformed... but never tarantulas.
i will have to take a look at the picture when i get home
I have only seen this once, and on her next molt she should produce a new straight leg. She may chose to cast off that leg if its in the way, but she looks very healthy other then the leg so she should be fine.
Container is not the problem it was just a weird molt.
EDIT, Caco got it in there above me to, but I have had things molt in transit and I keep smaller containers as well and that does not seem to be an issue.
Well, I have noticed that after all my tarantulas molt, they like to spread their legs out very far, as straight as they can get them. And they will sit there like that for a while. Couple of hours or longer maybe. Like they want to stretch everything out after that molt.
I too have to comment on the small space that spider has. I would move it to a container that has more width. At least enough for the spider to strech out.
well after my P.regalis got its leg broke it hid into the hollow portion of the plastic wood I expect that my T will be out in the open in a week or two but I was hoping that its leg will be fine the next time I see it
i don't understand how people can read that i have had spiders shipped to me that molted in a TINY CRAMPED FULL OF PAPER TOWELS shipping container with no problem and still say it looks cramped and that is what led to the trouble. i have a 7" ornata the made a molting hammock on top of two edges of cork park in the very top neck of a large jug and she molted fine... they typically molt in their houses in the wild, which are not very large at all.
the problem with this is that if there is a genuine problem that is overlooked then the spider might have problems on its next molt
