Her butt is clean, she doesn't poop in her cage as she's always lying in it.
When I take her out of the cage, she stands one second to poo, and goes back lying again one step away.
Her poo is liquid with little black or green grains, sometimes it's only black liquid (due to vitamins I guess).
I feed her a scrambled egg each day (cooked in sunflower oil), and 10ml water with vitamins (in a syringe).
She's 6 months old and lives with 3 other chickens : free run by day, bird cage by night (no bedding needed).
My little rooster stopped sneezing and is out in the garden today, after 2 weeks in.
My location is...Europe, France (you may already have wondered what kind of english I was writing). The weather is mild, 12 to 14° Celsius, no rain.
I will post pictures, my cellular lens is broken, I have to ask someone to take pictures
