confused-domino ooths being eaten before laid-while sticking out-only 5 adults in bin-no nymphs

[Amazing Nature]

so 2 of my newly acquired females recently had ooths carrying them about still

but both where half eaten/gone when I checked other day-but still sticking out-I could see inside ooth half still inside /white goop-fresh hollowed out egg case

right up to 'butt' end of roach-so def eaten-

 

I don't understand why ooths being eaten -

setup

its 3 male and 2 female orange domino in 12x16? Walmart bin (is this male to female ratio bad?)

with-

coco fiber/organic soil and soft white wood chunks substrate-and mix hardwood leaves/maple/oak/sumac on top for cover/food

they get rotation of banana--carrots-dog kibble-blueberries/etc and the always present hardwood-leaves

I don't think it's protein, maybe you're keeping them too dry.
