Today was about 35 degrees outside. Came to the hive took my sun glasses off and peeked into the top entrance hole. Nothing.. blackness.. dark.. kept my eye steady and strained to stay focuss in about one minute I saw bees moving slowly on the top cover about then slowly I saw the bees clustering like a large grapefruit between the top supper through the middle top cover opening and the telescopic cover. What a site.. some were shivering with their wings. Then I realized that if one bee decided to exit I would get stung right in the eye :shock:! Awsome sight. Spring is almost here.
