I buy 2000 crickets at a time and I put 1500 in a feeder bin and 500 in another bin an I have a dirt container in each bin. I switch them out every week, since it takes about 5 weeks for the crickets to hatch I have 7 incubating bins for the crickets so every week I should have new crickets hatching. After a week from the day they started to hatch I dump the pin head crickets into a larger bin and than reuse the dirt. The cycle has seemed to be working pretty good
