Estimate how many feeders your colony will produce and whether you're meeting your target demand. A rough planning tool to help you size your operation.
Other feeder tools: Check our Rack Space Planner to estimate capacity, and the Feeder Profit Estimator to calculate ROI for your operation.

You are under-producing by approximately 8.6 feeders per week compared to your target of 20.
With 10 breeding females producing an average of 10 pups per litter, 7 times per year, and a 85% survival rate, your colony will produce approximately 50 feeders per month (11.4 per week).
To meet your target demand, consider adding more breeding females or sourcing additional feeders from ReptileKitchen.
The calculator uses a simple formula: Monthly Production = Females x Litters/Year x Litter Size x Survival Rate / 12
Weekly production is derived by dividing monthly by ~4.345 weeks per month.
Based on published rodent reproduction research and breeder community data.
