Feeding Honeybees in the Spring

I try not to let my sugar H2O run out, especially if I hived my bees on bare foundation. I mix up a fresh batch of sugar water every 4 days and just lift the lid off of each hive to fill the sugar feeder (in the afternoon when temperature = 50* or higher) I will check for queen activity this weekend (4/24/15 - 4/26/15). At that time I will be holding frames up to peer into the back of wax cells to hopefully find eggs that look like small grains of rice or larva. These are both sensitive to sunlight so don't leave them out of the hive for too long. Just take a peek and place them right back inside the hive. Keep feeding sugar water for a several weeks.
