I need to contruct a cover type top over a outdoor pollen feeder that will actually sit inside the end of a pole barn. Out of the rain. I am having troulble with one of the local farms as the cows are vastly outnumbered at the feed bin.
I am not able to put new pollen in every day, so I was hoping to have something I could load up with 3 or 4 days worth of pollen, between visits. I am looking at something that the bees can go through, but keep the many mice from feeding on the pollen. I have numerous sizes in the garage but when it comes right down to it, I am not sure what size mesh a mouse can go through and which they can't.
Anybody want to run down which size mesh screen is best for which job? I know I use #8 on the screen bottom boards, but what does other use the other sizes for? Thank you.
