Two year old “Shy” is not eating or drinking this morning....
She’s always been so healthy!
Acting lethargic. Burying her head like this.
thank you...

I'm sorry, your photo is not showing up.

Hard to know what's happening - has the hen laid an egg recently, what does her poop look like, is her crop emptying overnight, no lice/mites, any bloat/fluid in the abdomen, could she have eaten anything toxic/molded/rotten?
