When you get a smaller swarm, do they tend to be more experienced in getting their own food? My friend just received one and she has been trying to get them to take syrup but they haven't touched it in 2-3 days. I told her because they days are so warm here to change the syrup in a few days because it might go sour, do you think a week is long enough to hold a jar of sryup? Our temps are running 60-70 during the day and 45-50 at night.
