Cold weather

Tonight it's getting down into the low 30s with snow predicted. I put a piece of coroplast in the slot for the sticky board under the screened bottom board. I also was looking at the hole where my syrup jar sits and figured out why the bees aren't drinking it - they can't! The holes on the jar lid are about 1/8" over the screen, and their little bee tongues can't reach the syrup unless it's dripping down. I moved the jar over the open hole with no screen. We'll see if that makes a difference. I figure with the cold rainy weather they'll appreciate the extra food. We'll see.
