21 days is the early end of the likelyhood of laying. Most of my
panther females lay at about th 30 day mark.
You could set her in the place where you want her to lay the eggs,
to ensure that she knows its there. You could also dig a bit of a
hole there and she might take a hint from that. Generally she
should find the place on her own, as long as she is above it at
some point so she can see that there is dirt/sand/soil there.
Some advice...once she starts digging, don't let her see you or
she could abandon the hole. If she abandons it often enough she
could become eggbound. Most panther females that I have had took
a couple of days to dig the hole...so don't worry if she comes
out and takes a break as long as she goes back and digs again.
Don't leave extra insects in the cage when she starts digging.
They might eat the eggs or chew on her while she is laying them.
(During the actual laying, they are in a sort of stupor and seem
to not notice that they are being chewed on.)
You are right about it being terrifying now...and the next time
won't likely be any less scary!
You said "How long should I wait before I put her in the standby
bucket if she does not accept the receptacle...say next thursday? It will be exactly 21
days on Friday"...its hard to answer that since each chameleon is
different in the length of gestation to some degree. If she looks
okay and is eating and drinking, you should be able to give her a
few more days. Like I said above, 21 is not very long. 30 is more
within the average, and some even take longer.
Sorry I can't be more specific about when to move her to another
egglaying chamber.
Good luck with her! Keep us posted!
Waiting for the eggs to be laid needs patience. Waiting for them
to hatch takes even more!
