Golden comet is lethargic. Will drink but not eat. Weird neck movements.

[Jfab]

Everything but neck movements started yesterday afternoon. No fluid build up in ab. I did catch her eat a baby frog Saturday. And before I could stop her she ate a lizard Friday. Could this cause the problem? Please help.

Is she pooping?
What does her crop feel like?
How old is she?

Could be adjusting the crop due to blockage. Read this and see if you need to start treatment. https://www.backyardchickens.com/ar...w-to-know-which-one-youre-dealing-with.73607/

She is 4 years old. She just pooped. It was not solid. White and brown. But she hasnt eaten today and not much yesterday. Her crop is not hard or squishy. Just feels like loose wad of skin with slight bulge.. When i massage that area or pick her up she drools almost clear liquid. She walks around a little and then looks like she's napping. She has quit drinking.

Doesn't sound like the crop is empty then. I would treat for crop issues, but likely she has something else going on that is causing the crop to slow. Reproductive disorders can be common.
Just in case, look inside her beak to make sure there's no lesions, canker or yellow pasty material as well.
