I’ve almost completed painting my bait hive brood boxes now. At least, I thought I had: six of them.
I was sorting through them in the apiary after the bees had gone to bed this evening and found at least one more brood box with ½” thick walls. It’s full of old brood frames at the moment, but I was pushing the light and couldn’t really tell what sort of condition they were in. They were narrow top bars whereas I now prefer wide ones, so I don’t think I’ll be using them in hives again, but if they’re in good enough shape they might be ok for more insulated dummies.
Having more bait hive boxes is not a major issue. It means that I can swap the complete box out to move it if necessary, rather than having to shift the frames to a new box straight away. Gives me a little bit more flexibility.
