how often do you feed?

hey! i’m new to owning leopard geckos and i’ve had many different people tell me different things. i was gifted my geckos, and they’re about 4 years old (1 male 1 female.) how often do you guys feed your adult leopard geckos? i’ve been getting about a dozen a week and dumping them all in the tank at once. feed days are usually every sunday. is this okay? any feedback helps, thank you!
