I was just wondering how common is AFB? Is it something that is a serious concern i.e. easy to get or is it something simply to be vigilant with? I made up a nucleus hive the other day and they've kicked out a few pupae from the front entrance (only three) - one had their tongue sticking out - but their colour and form was fine, no odour, all of the cappings on the brood frames are fine, the donor hive is fine - i think it's just general hygienic behaviour post releasing the introduced queen and in preparation for her laying - but it got me wondering. Also, i would assume it's normal habit for them to 'evict' dead brood - i only noticed it because of the way i have the hive positioned - but what would be a 'normal' eviction rate? a few here and there?
