Help! Hen went from great to barely surviving

[mmatlock13]

1)She is a sapphire blue rock, about 1.5 years old and has gotten lighter in 2 days.
2) I found her roosting very lethargic. She can stand and can walk but really won’t. Barely eating or drinking. Her tail is down and as time passes, comb is falling and slightly discolored. She gets white crust at corner of her beak(?) but no smell or internal mouth discoloration. No egg laying as far as we can tell
3) this is going on a day and half
4) rest of flock seem fine
5) no visible injuries
6) no idea what happened
7) she will only drink a tiny bit of plain water
8) her poop seems normal except a tad more yellow

See attached pictures, I tried the best I could. Her eyes weee only closed because she was comfy and resting. Thank you for any help!

I'm sorry to hear that. What's her diet? Has she ever been wormed? Have you tried vitamin therapy?

She gets Naturewise feather fixer. I haven’t been able to get vitamins in her and honestly she hasn’t been dewormed. Truthfully these are my first chickens and I didn’t know what I didn’t know what I didn’t know. Trying to fix that

Is she standing funny?

Just like she’s weak, maybe a tad wide leg. I checked to see if maybe egg bound and as far as I can tell, there isn’t.

That's so strange.
Try some b complex tablets or nutritional yeast, from the grocery store, maybe it will perk her ip.

Thank you! I’ve been searching myself to death and all her symptoms are all over!
