Early stimulation of bees is not necessary a good thing. If you have a need and use for early bees to make nucs, splits, or packages then stimulate feed the girls. If you do not have a purpose for the early bees all you are doing is increasing the swarm risk later on in the season. Beekeeping is about having a plan for your operation and what you want out of the bees and hive and then implementing and sticking with it.
The beekeeper that lets the hives dictate his or her management are more apt to fail. I want honey... Oh Queen cells, Lets raise some nucs, nucs are produced late so no market, To many bees removed from colony so no honey. nucs don't build up enough so are lost during the winter. With all the extra manipulation The treatments are missed or to late and the hive might not make it.
Have a plan, Stick to the plan, manipulate the hive to follow the plan... But also be mindful of inspecting for disease and mites, that the queen is laying to her full potential, and that you do every thing you can to help the hive be successful in following your plan.
Sorry Les got a little carried away with my rant. If he has kept bees in his area for a long time he may have Knowledge that pollen is missing in the early spring but feeding syrup is only required if the hive is very light. Over feeding then the spring bloom hits and the brood nest becomes honey bound, that causes swarming issues.
I would suggest asking him why he does what he dose, it will most likely be very enlightening and will let you in on some secrets of your area.
