Guinea Fowl and Bees

Guinea fowl and honey bees.
My friend's guinea fowl from next door have decided that they like my garden too, so they are now a shared interest. I am finding them fascinating and quite pleased to be sharing them but my worry is that they may eat my bees - i have 2 hives in my garden and last summer we had a big problem with magpies picking live bees off the step of the hives. So far, so good the guinea fowl seem to stroll past without noticing them - but will this last?
We live on a farm so the guinea fowl can roam a big area. We have a temperate climate so probably not so much wild food around in winter.

Maybe a screened front porch for your bees, made of 1"x2" welded sire, extended out about 10" from the hive entrance. Position the with the 2" opening running horizontal would prevent the birds from getting a lip lock but allow the bees to fly in and out.

Thanks Tracy, the could be a very simple solution and will stop any more magpies raiding the hives too.
