One of my hens is sick. Her crown is limp, she lays on her side and wont move. Barely eats or drinks. What do i do?

Do you have photos?
How old is she>
What do you normally feed including treats?
When was her last egg?

Hard to know what's happening with her.
Work on hydration and see if she can perk up.

Have you ever had this happen with any other birds in the past?
