hi Rebecca,
Welcome to TDKland. We’re the furriest forum around!
Few kits like to be stimulated to poop. When you check out this video you’ll see how squirmy and loud they can be.

A smidgen of mineral oil in their milk or cat hairball formula on their lips can usually help them poop. You can put a dab of Neosporin on their bums for soreness. Now it’s possible they’re constipated. KMR concentrate tends to give kits constipation and the liquid does the opposite. Here in TDKland, we recommend Goats’ milk for kittens. Cats are lactose intolerant and can’t digest cows milk. Goats’ milk is full of nutrients, probiotics and gentler on their tummies. This can also regulate the poop. You can find it in the dairy section or the concentrate in the baking aisle. Mix the concentrate 1:1 with water or pedylite.
If it’s been longer than 5 days, you need to call the vet. Sometimes, that first one is hard and they can’t get it out.
You’re off to a great start. Thank you for rescuing the wee girls. Purrhaps we’ll see them as our Daily Kitten(s) soon.
Good luck,
PG
