If you have a bee shed like me you can have an entrance inside this will allow the bees to fly inside the shed , i have not tried it yet but they have used bee sheds abroad for years is there anyone out there apart from me that uses one, i did a quick inspection of the hive three weeks ago in the winter warmth, my ladies have a good amount of stores but looked to be running low on pollen so i have put 250 grams on top of the brood for them. i dont belive in putting gallons of syrup on top of a brood bow in the spring any way they take it down there is not much room for the queen to lay my lot store it every where, its better for me to use a 300ml jam jar and to fill this up every few days that way thet have enough for the present needs and a little bit to store
