What sugar to water ratio would I be best using to encourage my recently separated (5 weeks ago and full of eggs but no capped brood, enough food stores in the brood chamber, but foundation in super not touched/drawn out at all) hives? One of them is a bit low on bee numbers, but has loads of eggs, so some feed may help them a bit.
Does 1kg sugar to 1ltr water sound about right? And contact feeder or rapid feeder?
