Re: How to know if they are getting enough pollen?
(What I'm concerned about is if they have been living so much on the feeders, how can I tell if they are getting enough pollen?)
Keep an eye on the them as they come into the landing board or entrance. Most days I'd est. my 40% have pollen baskets filled and the others usually have some. If they are going in too fast for you to see, take your camera and get some pics, take a bunch and you'll may be surprised how much comes in. Obvious you can open up and pull frames for confirmation. I'd rather look as they come in. Less disturbance. Sometimes it takes a day or so after periods of rain to see them gathering again. And you've had some rain up that area.
I'd skip the patty till later. SHBs love em.
