I wanted to feed some old honey to a couple of light nucs. A local 30 year beekeeper had told me about using quail waterers for syrup and thought the one quart size would work well. It turns out they worked very well. It's getting down to the thirties at night occasionally so I put a piece of cardboard on the top bars to help hold heat down. The quail waterer sits near a hole cut in the cardboard with a covered empty nuc body around it. One nuc took to the honey right away and the other took about a day. Now they are both staying busy night and day. Replaced one empty jar last night and had several bees in the jar. I shook the bees out, but then decided to lay the empty far on its side so they could finish cleaning it out. I found a few posts about quail waterers, but thought this might be worth passing along. The waterers are available in quart and gallon size online. My friend Joe says the quail waterers won't drown bees like chicken waterers because the space is narrower. I haven't seen more than one or two drowned bees. A screen ring would keep bees from getting in the empty jar, but it isn't a big deal to shake them out either. Best price I've found was $1.49 I think for the quart lids without a jar.
It's been interesting to see the beard like chain of bees coming through the hole to the waterer.
