Warre hives are criticised for letting the bees store honey in "old brood comb", totally overlooking the fact that incoming nectar is initially stored in brood comb and only later moved by house bees to the supers.
I am a bit surprised that you can't distinguish between the method used by bees to remove honey from a brood comb and those used by humans. Further there is no law against frames being used without foundation nor is there a law that supers must be used for 30 years. If conventional equipment is used thoughtfully you can have clean honey and look after the bees properly at the same time.
When you squeeze honey from a brood comb and get black streaks in it have you ever bothered to analyse the contamination to see what it contains? Until someone does I suggest none of us should feed it to babies.
I have other issues with both warres and top bar hives but they don't belong in this thread.
