Finman, you have made almost a third of the posts so far on this thread.
When are you going to realise that feeding protein to bees if they need it is good, otherwise, a waste of time, cost and effort?
When are you going to realise that I would feed pollen substitutes to my colonies if they were short of pollen?
When are you going to realise that extra protein is not always needed for bees in the UK because we have a different climate to Finland?
When are you going to realise that beekeeping methods are somewhat different in Finland and the UK? And for that matter the US and Australia?
When are you going to realise that, for many, feeding protein is not necessary because they don't want to accelerate the spring expansion before there is loads of pollen, freely available, for the bees?
And, BTW, if my hands are quicker than your brain, you are likely in a bad way!! Have a nice day, perhaps go and make some pollen patties? I will not be making any pollen-substitute patties unless the bees need it. Others may feel theirs need it; a matter of observation and fairly simple decision making - nothing too difficult, I would think. Bye for now.
