What defines a healthy colony

[Wilco]

Hi all,

Just wondered if people could post what criteria they use to determine whether a colony is healthy?

Background - trying to come up with a relatively objective metric for colony health as part of my PhD student's work into honey microbiome.

Also - does anyone have an exhaustive list of hive monitoring tech?

TIA

But what do you mean by healthy? All colonies have endemic pests and parasites.
The question may be in the answer
