Thank you for my morning laugh!I've never heard of them, so of course i have an opinion (this is the internet, afterall)
Looked it up and i wish they showed them on a Langstroth. They appear to be a fancier way to do the same as the jar on the top of the hive feeder (e.g. https://www.kelleybees.com/quad-hive-top-feeders.html). They go right along with the boutique hives they are pictured with.
He might have to get rid of his internet. I hate mieces to pieces.I really find it hard to believe that anyone was that offended that easily. And I don't care about anyone who is offended that easily sticking around. We have reinvented mousetraps so many times that mice would be extinct, if they worked.
I apologize for my next comment but my sarcastic side could not be stopped. You are just learning about beekeeping and the first question you ask is about the Hartman Beehive Feeder? Really?No I'm just learning about bee keeping!
and Thank's for being an jerk see ya I'm leaving this site thank's to you!!!
