Both of my hives are still draining the top feeders in 2-3 days, but that isn't a major concern as they are both brand new hives. 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? Also, I want to make sure we have enough food sources in the area that they can survive without the feeders next season. We have had an incredibly rainy spring/summer so I am chalking a lot of it up to that but still, I am concerned they won't be able to survive without the feeders next year. Should I just throw some pollen patties in there? Thanks!
