lets talk numbers. most of the balls i have seen are 300-600. lets call it $1000 for a pair. i've seen videos about complete terrariums for $100. this is assuming i want to do a terrarium and not a plastic tub. bags of 50 feeders are less than $50 and last 6 months so $100 a year. balls lay 4-6 eggs annually. i sell babies for $200-500. my breeders live 20-40 years. how is this a losing situation?
