Do males hatch with the bulbs on the pedipalps? I've gotten the impression that this is not right. So do they develop them after a molt? If so, at what size can you sex them? We just got an A. avicularia that is about 3 inchs long and we are trying to determine the sex. So far we believe it to be a female, but I only paid $12 so I wonder.
Thanks for any input.

welcome to arachnoboards!

Males do not hatch with palpal emboli (bulbs), they get them when they mature, with their ultimate molt.
After that males (normally) stop molting, so their livespan is shorter than a female's.

You can sex a tarantula from the inside of a molt or it's underside, but that's tricky!
I suggest that you use the search function, there is a lot of information regarding sexing on this board!

If you need to when it moults some dealers on here do free sexing so u can send the moult to have it sexed. I would say a good size to sex from is 2.5"-3"
