So I was going to the bee yard, everyday, observing (leaving the hives alone), and taking Broodminder readings; we noticed the inside humidity was fluctuating on both hives, and we saw some bearding on the outside of the hives; then it dawned on us…..
We have screened bottom boards, but we forgot to remove the mite boards from them, and the airflow was a bit restricted; so, we removed the mite-boards, and opened up the entrance reducers to the next size.
We had to get to the hives anyway, because today was when we decided to remove the queen excluders that we had put at the bottom of the hives (between the bottom board and the bottom of the brood box (the bottom-most box)), to ensure the queens did not leave over the first couple of days.
This should make it a bit easier on the bees to regulate the inside conditions.
