I saw one of my domino's with an oothecae yesterday, the only thing is is that i dont know if i have any male, i brought them as adults so their might of been males before i had them but do they produce infertile ooths?

I could be wrong, but I don't believe they will..... if they were mine I would assume the ootheca to be fertile. This is an Orin question....

I had thought that that ooth was the only one, but i had a root through their enclosure yesterday and discovered these
How come some of them are fatter than the others?
Is this a sign of the young developing inside maybe?
Plus are they safe incubating in their enclosure?
Or can i take them out and incubate them like phasmid ova?
