Yellow dots in yellow-tinted urates on stool?

[charlotte-and-the-bees]

Hellooo me again with repeat issues. We’ve had a series of sick hens over the past few months, multiple vet visits and just did a round of worming for all. I noticed these yellow dots in the stool of one just now, not positive which. Any idea what they are? I searched on here and couldn’t find anything comparable. Thanks!

Looks like oil to me. What have they been eating?
