Well i have a female ambilobe who runs for my hand when i open the cage but she prefers to sit on my shoulder to being ''held''. My sambava male will climb onto my hand of his own free will if you stand there for like 5 minutes and let him take his time to decide for himself.
Personally i prefer playsand for their egg laying...it seems to stay in better shape for no tunnel colapse and they seem to be able to move it around easier. Needs to be damp though.
Well until monday give her complete privacy...she may not be finishing because she keeps seeing you. If they think you know their laying site they will abandon it.
