. So i guess i will do just that i wanted to give them until the end of june to see if they will both build up enough to make it thru the winter.
The "build up enough for winter" is very easy. You have there long summer there. We have here just apples in blossom.
If you change the queen it is better to do now. It influnces on the yield of August if you have then nertar flow.
Don't be too modest. Look at this picture. Here is small colony 2 months ago it was snow in groud. Now this weekend it will have 3 boxes.
Colony is not able to raise so soon by it's own help. I gived 3 weeks ago emerging brood frames from bigger hives and so it got kick up.
Now I have 2 swarming hives. I take a box of bees from swarmin hive and I give third box which is empty.
I can do this the queen is good. And it is. I waist my bees if I nurse weak queen. So you see that basic is the queen and you may help it.
So get the new queen as soon as possible and construct your hives on good basis. If queen is not good it does not get better by waiting.
It is delight for eyes when hive raises.
You should get hive to occupy one whole box. So it developes well. 5-frame colony is too slow to develope. You may take aid from bigger hives.
