I went outside yesterday to put a bucket of water out for the bees only to find a big beard on the solid bottomed hive. The hive with a screened bottom had nothing.
I pulled some bars out and put a window screen across.
Then I propped the screen up with one of the top bars (some mulch and grass stuck to the propolis) Hopefully this will make them a bit more comfortable today. It should be much cooler after tonight.
