Happy hen, milky white poo

[PoppySeedy]

I've recently noticed a few milky white poos around my chickens run. On the first day I saw them I wasn't too concerned since weird poo is normal but I saw a lot again today and decided to ask here.
All the girls look physically healthy with bright red combs and they're all acting normal.
I got eggs from all the girls today but recently the laying has been a bit skewed due to bonfire night and I assume the fireworks scaring them/making the hens uncomfortable.
I'll attach a picture of her poop, any ideas on what it could be?

This can be from stress, however, worms and other internal parasites can cause this too. She also may have not been eating much at the time, making her poop more “milky” or watery than usual. Keep an eye on her, offer vitamins and probiotics to improve gut health and watch to see if her poops improve.

Okay, I've tried giving them bananas and putting a gut health liquid i have into their water and im still seeing milky poops. Should I consider deworming them before winter hits and if yes, what dewormer would you recommend?

I’ve used Ivermectin this year. I suggest it
