Thanks Nigel, that is interesting but I'm still being a bit thick here.
Is the suggestion to incrementally turn the hive entrance through a 90 degree turn - where they are currently located in the garage? If so, what would be the point as they'd eventually learn their entrance is just around the corner but they'd still be located where I don't want them to be.
So, should I move them up to the apiary at night and place the hive at a 90 degree turn to what it was when it was in the garage? This doesn't seem to make sense to me either as the entire hive has moved 50 feet - so what would the difference be in turning it?
I do get the importance of them working on a section of forage and having a stronger memory to return to the garage, then once the forage is done, they might be easier to relocate - but at what point and where should I turn the entrance?
Sorry to bang on - but it's interesting and I'd like to know for the future, they will be off down the road to my mates soon, so it won't apply this time. But it might another day.
