Hello! I love feeding our girl's soldier fly larvae . I personally prefer black soldier fly larvae because it has 75% more calcium than mealworms. They absolutely love it and it's healthy for them too! I feed about 5-6 black soldier fly larvae per hen daily. I don't raise my own mealworms though I accidentally did once when flies got into one of my feed Tupperwares, laid eggs, hatched, and then I got live mealworms that our girls loved. I usually buy dried mealworms and recommend the brand Grubs Terra. It comes in huge bags and Our girls go crazy for it.
