My aliens have an egg pouch and they can lay up to 15 eggs in a clutch. Those aliens inside the eggs eventually become newborn human sized, at least as far as length is concerned. I was wondering if skin shedding and growth would work for this.
See, what I think would happen in a female alien is that once her milk ducts start maturing and she starts ovulating, is that the skin of the pouch would shed more frequently than her body due to female hormones circulating. And since shedding often means growth(though of course, adults do shed as well), the pouch would be growing until it can hold 15 eggs and later 15 babies.
I had dry skin yesterday and the itch I had from it was driving me nuts. I am sure that my aliens will experience a similar, all over itch when they are about to shed their skin.
But would increasing the pouch skin shedding rate(and thus growth rate) in response to female hormones actually work for holding eggs and later babies in the pouch with less pain?
