Flocculation immediately??

Hey guys,

I started a Brew House Red Ale using Wyeast Irish Ale 1084. I did a starter as well for this one with an F.G for the starter at about 1.10. I aerated pleny and setup my 6g carboy. Afer 20-30 mins I notice that there is a 1/4-1/2" Trub-like settling of the yeast already. The website says low-medium flocculation. Should I be seeing this already? If so, should I be shaking the carboy often until I see krausen to distribute the yeast so it can feed, then leave it?

Thanks in advance!

My guess is that it's probably not yeast just break material transferred over from the kettle.

That is cold break not yeast
