Preheat the oven to 325°F (163°C): Lightly grease a small baking dish or line it with parchment paper to prevent sticking.
Mix the dry ingredients: In a large mixing bowl, combine the chicken pellet feed, scratch grain, sunflower seeds, black soldier fly larvae, flour, cinnamon, cayenne pepper, and crushed eggshells. Stir well to evenly distribute the ingredients.
Add the wet ingredients: Pour in the molasses and melted coconut oil. Stir until the mixture is fully coated and sticky, ensuring that the molasses binds everything together.
Shape and press into the pan: Transfer the mixture to the prepared baking dish. Use a spatula or your hands to firmly press it down into an even, compact layer.
Create a hole for hanging: Before baking, insert a greased metal straw, dowel, or the handle of a wooden spoon into the mixture near the top, ensuring it’s large enough for a rope or twine to pass through. This will create a hole for hanging the block later.
Bake for minutes: Place the dish in the preheated oven and bake until the mixture is firm and slightly darkened. The block should feel solid when gently pressed.
Cool and remove the hole insert: Let the flock block cool in the pan for about 30 minutes. Then, carefully remove the straw or dowel while it’s still slightly warm to keep the hole intact. Allow the block to fully cool and harden for at least 2 hours.
Add a rope and hang: Once fully hardened, thread a sturdy rope or twine through the hole and tie a secure knot. Hang it in the chicken run for your flock to enjoy!
