I am considering breeding crickets for my daughters Lizards (Gecko's) and was wondering what is the life span of a cricket and how long does it take them to grow up she goes through 3-5 crickets per day per lizard 4 are small house geckos eating small crickets that are in for the winter and a leopard gecko eating large crickets we buy approximately 60 crickets a week from our local pet store and she is looking at spending her next savings on another leopard gecko so it is looking like it will in the long run be cheaper but from what I have read you have to remove the adults before the babies hatch too prevent cannibalizing of the babies or is this not necessary if there is plenty of room and food for the adults and babies. Any help appreciated or ideas and setups.
