I bought two nucs 15 days ago and installed into my new hives, the nuc looked really good, heavy with capped brood, honey and pollen, last weekend I checked the hives, all the brood was hatched, but I didn't see any new eggs. Today I checked again, no eggs, no larvae and the bees are not drawing out the new frames. Could I be queenless? The bees are storing necter, probably syrup and pollen in all the cells where the eggs should be. Help please!!
