Hello all, I am fairly new to keeping crickets so I'm not sure what I might be doing wrong. When I first got the crickets about 2 weeks ago I was keeping them in a large Exo Terra cricket pen and feeding them Flukers Orange Cubes, and also was using paper towel as their bedding. They started smelling because of poor ventilation and dirty bedding so I moved them to a different pen, completely cleaned out the container. I didn't change anything except the bedding, which I switched to steel-cut oats as I had heard oatmeal bedding was good for keeping away smells and also a good source of food for them. I also moved them to a better ventilated area that was more temperature regulated. Before the bedding change I hadn't had any problem with them dying, having only found one or two dead at the time of cleaning them. It's been 3 days since then and I've found 3-5 dead every day. I'm not sure if they were just sickly beforehand or what, but I'm very confused and worried.
