Pullet just ate 4 oleander flowers! Will she be ok?

[Haleyrbloom]

One of my pullets got out of the run and was able to eat 4 oleander flowers off the ground.

By the time I could catch her, she had already downed them.

Will she be ok? Anyone have experience with chickens eating oleander?

Can I give her something that will absorb any of the poison?

She seems fine right now, but worried about her.

She is panting, but it is hot outside.
She has ice, water, a fan and shade.

Any signs to look for if she does get sick?
