My cham loves being held:)
When I open the door she walks right onto my hand. So, yes it is possible. But they all have different personalities. Maybe try hand feeding her so she knows your hand brings food:)
Can you add a picture this may help. I'd personally change to vermiculite. That's what I use while incubating. Sometimes an egg will mild a bit but then be saved. If it's heavily molded it's probably infertile. But if your switching to vermiculite it wouldn't hurt to divide them to keep the mold...
It doesn't say on the site how many cages I could set the pp up to with aqua zamp. I do plan to have a good number of Chams:) so I'd rather buy the right system from the get go rather than upgrading later.
So the aquazsmp or mist king for multiple Chams?
