HELP! Bantam Cochin - ruffled feathers

[TheChickenGirl16]

My little bantam Cochin girl is almost 8 weeks old.
She seemed perfectly normal yesterday, but today, while she did come out of the coop, she immediately went to her favorite box to sit in.
Her feathers are ruffled, and she doesn’t seem interested in food.
She lives with 25 other chicks of different breeds, but most of them have been together since hatch, and I’ve never seen any of them pick on her.
Any ideas?

I also found this weird thing on their dropping board…

She’s come out to find a sunny spot, but is laying down kinda weirdly…

it might be coccidiosis i would get corid asap

 

[TheChickenGirl16]

Okay thank you.
She just passed.
I will try to find some Corrid to give everyone else.

So sorry she didn't make it!

I agree with @Beau plus penny. It's probably coccidiosis, so get some Corid as soon as you can and treat immediately.

I can only find Corid for calves.
Is that okay?
