Egg bound hen… getting worse not better

[Calliechristine]

How is your hen doing today?

Thanks for checking, sorry I’m just now seeing the message. She did about the same Monday and Tuesday and she had been doing. No improvement, but no worse.
Today (Wednesday) she’s significantly worse. She’s barely moving, and will only drink or eat a bite before laying back down and closing her eyes. Very slow, heavy breathing too.
I don’t know what else to try - been keeping her bum clean, giving calcium and Vit. D3, and lots of food and water available. I’m thinking she won’t last the rest of the day.
