Thanks Dalon and Wombat for your great replies!
Went in today and put a super on top of my strong hive. I scraped the burr comb out of the roof and on top of the frames and put it all back in on top of the super, hopefully the bees will be able to recycle it. The frames in that hive were really stuck in there, so I will need to go back and do what Wombat suggested in terms of swapping brood frames out.
Have another problem though. On my other hive, I had a look in and not as strong as the first hive, but certainly still looks healthy. Problem is when I tried to remove one of the frames the top bar popped out. Tried to get another frame out and same thing happened! Realised too late that they are stuck on bottom. For the life of me I couldn't get the two brood boxes apart.
I've just read about using wire technique (running a piece of wire between boxes) so will give that a try once they calm down tomorrow. What I'm not sure to do about is the two frames that I popped. Once I get the wire through they will be easier to remove, but is there a way I can get the frame back together while in the box? I went back with a small drill and a couple of small screws, but the bees were ANGRY. Thought it best to try another day.
Do you think that screwing them in will work, just to get them out? Are there any other tricks that anyone can recommend that wont be too disruptive to the bees? I will swap them with replacement frames once I get them out, and will spend today cleaning up a spare bottom board to swap over.
Any advice appreciated. In my third year of amateur beekeeping and still have so much to learn!
Thanks
Jim
