Hi,wondered if i could get advice on how long i should feed new bees ?We put a five frame nuc in the main hive andit has been in there for three days .We had a blip with first feed leaking and put new feed on .should we look tonight to see if the bees need more or leave alone?also a few bees crawling about on the floor looking not well ,.although the rest of bees look to be very busy . We have omf and on floor underneath is lots of yellow bits is this just normal waste?sorry about so many questions all at once.
