I have a month old clutch of haatchling bps. Only one of them has taken a third meal. I recently switched them from paper towels to aspen bedding. Im worried that the rat crawlers will be too hard to find when nestled in the bedding. Am i correct in assuming this? Should i go back to paper towels? The one visual hatchling i hatched is the only one to not take a meal on its own yet and id hate to delay it anymore by using the aspen.
