Foamy medium brown poop

[Cuween]

I’ve recently within the last few months treated a hen for worms and Coccidiosis. She has all normal poop—dark brown with white— but she has small amount of foamy medium brown poop at least once a day.
Is this normal or could it still be the C. or worms.
I will be taking sample to vet to make sure. Just wondered if anyone else had seen this in healthy hens?

Could you get a picture?
It just sounds like cecal poop to me, which is completely normal.
