Ok I work at a petstore and have access to cheap bugs. I always bring home bug treats for my ducks and they go crazy for them. Its a cute little game we play. I let the bugs go and they chase them through the grass or eat them out of my hand. I want to know what kind of bugs are the best. Iv heard crickets have niacin in them but I cant find any proof of it. I switch it up from meal worms to crickets and have been thinking of giving them some feeder fish but idk. Also heard meal worms can be fatty so I dont give them much bug treats.
