I just bought 30 bags of Omalley pellets from a reputable dealer here in MD (Courtland Hearth/ Hardware). While unloading the pellets at my house I found that several bags, maybe 8-10 had hard chucks of pellets inside. It felt like the pellets were frozen together, it has been in the mid 20's- 30's here for the past few weeks. Is this bad? or can I just store these bags inside and let them thaw/ dry until use. I usually store my pellets in the garage.
