Bush, so sorry for the loss. We have all made mistakes. I would (did) inspections as soon as weather permitted. I saw winter loss, bees frozen in cluster with honey close. One hive died of condensation, my largest, only, carni hive. Their lid was vented, however the bees sealed the vents and I placed a sugar patty above the cluster. The condensation formed off the patty and the rest is history.
Winter inspection would have saved this hive, but I do not conduct winter inspections so the hive was lost. I shoveled out dead bees, handful after handful of moisture soaked bees and found my beautiful solid black queen. Such a good layer, honey producer, I was sick also KNOWING my sugar patty above the cluster was cause. My other hives also had sugar patties, they did fine with small ventilation vents that were open.
Now understand this is not a lessen to ventilate your hives. This area has horrible humidity. My purpose is to demonstrate I make mistakes, we all do.
So Mr. Bush, been there, done that, DONT GIVE UP, Buddy. In your shoes I would have done the exact same thing.
Blessings
