My kiddies have all sorts of ‘stuff’ going on with their poop. I make note of it but unless they are acting off I just check again if I see them pooping.Tina tried to lay an egg todayand there's a bit of red in her white part of her poo but maybe that's the carrot

Poop can change so much with things such as temperature, food they eat, stress from molting, being broody (we all know those smelly poopies).
For your photos they both look splendid

Try not to get tunnel vision and see things that may or may not be there. I am good at that with the horses, if they cough, roll, look tired I used to get all bent out of shape that they might be ill - my Vet finally told me to stop looking at them hahaha.
