In the Brooder
hmm, well that's interesting, because kahm yeast is aerobic, so it likes air. Unless what you have there is not kahm yeast, in which case I would be a little concerned...
Could you take a photo of the yeast undisturbed and before you stir it in - if it show up again?
I actually attached a picture a couple days ago. I'll attach again however this mornings yeast I didn't get a picture. It looked like a light dusting on top. Similar to the picture I'm attaching just less dense
