First question, where you live what kind of flowers are blooming? How long is grass?
One of my hives is pretty weak, the other is doing much better.
Take extra frames awy and restrict the bee room as big as they have bees. Here I have medium wall and terrarium heater as aid.http://bees.freesuperhost.com/yabbfiles/Attachments/mediumwall.jpg
When bigger hive gets new bees give one full frame of emerging bees to tiny. It helps much. It should be 8 frames bees and so it runs itself.
Last March when we had nice and warm weather and both hivs were active I was getting nervous about them running out of food earlier this year, so I put a top feeder on both hives.
When you open the hive and you see capped food in hive, it is OK. Don't feed.
And when weather is good, it is time to look how much they have brood, how much food and vain room.
When you have whole box bees, it is good if they have 2 full frames of food = it is about 10 lbs. (langstroth). You calculate all frames together and valuate food situation. Extra food store limis spring build up.
I am wondering though if they just take it and store it in the super?
Open hive and look wat is inside. I suppose that they have brood in super. They start egg laying in warmest part of hive. And dont put exluder now.
some capped frames in the super on my strong hive.
In this situation they need not more food and it helps nothing.
but continue to feed syrup (and for how long)?
Calculate now both hives food reserve. You can even fod frames between hives, but dont feed too much. It just limits spring build up.
Thanks in advance for your answers.
