Do you have enough sugar stores in the hive?
It is February and hive should have 3 frames full of food. It means about 7 kg sugar.
It depends on amount of brood, how much hives use during winter months.
If the hive has 2-3 frames, do not feed, and if not, give at least 5 kg sugar as syrup.
Extra food constricts brooding area and there must be room to store pollen too.
If hive has too much brood frames, take one or two capped frames off.
So it goes. No one in internet knows what is the situation in your hives if you do not look inside.
