Commercial flock blocks cost $8-15 each, but backyard chicken keepers know these treats are essential for enrichment and nutrition. Whether you’re stretching your chicken budget or want to control exactly what goes into your birds’ treats, making your own flock block at home is a straightforward project that takes just 15 minutes of active work. Your flock will peck at it for weeks, staying entertained and well-fed without breaking the bank.
How to Make a Homemade Chicken Flock Block
Creating a flock block requires only a mixing bowl, mold, and seven basic ingredients you likely already have. The key is proper compression to create a dense, long-lasting treat block.
What You Will Need
- Mixing bowl (large enough for several cups of ingredients)
- A mold or container (PVC pipe, 4-inch diameter works well, or a cardboard tube)
- Parchment paper or newspaper for lining
- A pressing tool (tamper, wooden spoon handle, or similar object)
- Whole grains and seeds (oats, cracked corn, sunflower seeds, flax seeds)
- Unsulfured molasses or corn syrup (the binding agent)
- Optional mix-ins (crushed eggshells, herbs like oregano, chopped vegetables)
Steps
Prepare Your Mold
Line your mold or pipe with parchment paper or newspaper, leaving 2-3 inches extending above the top. This prevents sticking and makes removal easier later. If using a PVC pipe, you can stand it upright on a flat surface or place it on a cutting board for stability.
Combine Dry Ingredients
Pour your whole grains and seeds into a large mixing bowl. Use roughly equal parts oats and cracked corn (about 2-3 cups each), then add 1 cup of sunflower seeds and 1/2 cup of flax seeds. If including optional ingredients like crushed eggshells or dried herbs, add them now and stir until evenly distributed throughout the dry mixture.
Add the Molasses Binder
Drizzle 3/4 to 1 cup of unsulfured molasses or corn syrup over the dry ingredients while stirring constantly. Start with less and add more until the mixture holds together when squeezed but isn’t overly wet. The mixture should resemble thick oatmeal, where clumps stick to each other but don’t feel sloppy.
Fill the Mold
Spoon the wet grain mixture into your prepared mold, filling it about one-third of the way. Use your pressing tool to tamp down firmly and compress the mixture. Repeat this process–add more mixture, press down hard–until the mold is completely full and the block is densely packed with no air gaps.
Final Compression
Once the mold is full, press down on the top with maximum force for 30-60 seconds. The denser the block, the longer it will last in your coop. You should see the mixture resist when you press, indicating good compression.
Set for 24 Hours
Cover the top of the mold with plastic wrap or newspaper and let it sit at room temperature for 24 hours. This allows the molasses to set and helps the block firm up. Avoid moving or jostling the mold during this time.
Remove from Mold
After 24 hours, gently push the block from the bottom of the mold, using the parchment paper to help ease it out. Peel away the paper or newspaper. Your finished flock block should be solid and hold its shape.
Install in the Coop
Place the flock block on the ground or hang it from a string/wire at pecking height in your chicken coop. Your birds will immediately begin working at it. A block typically lasts 2-4 weeks depending on flock size. Store extra blocks in a cool, dry place where they’ll keep for months.
- If your mixture seems too dry and crumbly after adding molasses, microwave it for 20-30 seconds to warm and loosen the molasses, making it easier to mix.
- Use a 4-inch diameter PVC pipe as your mold–it’s the perfect size, inexpensive, and creates blocks that hang easily from a carabiner or S-hook.
- Add crushed oyster shells or calcium-rich kitchen scraps (like dried eggshells) to boost your hens’ egg production and shell strength while they peck.
What to Look For in Flock Block Supplies
- Mold Type and Durability: PVC pipe is the gold standard because it’s food-safe, reusable for hundreds of blocks, inexpensive, and easy to clean. Cardboard tubes work as single-use options but break down after repeated use.
- Grain Quality and Freshness: Buy whole grains and seeds in bulk from feed stores rather than grocery stores–they’re fresher, cheaper, and free from additives. Check for pleasant smell and absence of mold.
- Molasses Type: Choose unsulfured molasses specifically, as it’s cleaner for animals than sulfured varieties. Avoid blackstrap molasses as it’s very thick and harder to mix into dry ingredients.
- Cost Per Block: Homemade blocks cost $0.50-1.00 each versus $8-15 commercial blocks, but investing in a reusable mold and quality tools upfront saves money over a season of chicken keeping.

Frequently Asked Questions
How long does a homemade flock block last in the coop?
Most flock blocks last 2-4 weeks depending on flock size and pecking intensity. A block for 6-8 chickens typically lasts 3-4 weeks, while larger flocks finish them faster. You’ll know it’s time to replace when only crumbs remain or the block has been reduced to less than 1 inch tall.
Can I add kitchen scraps or garden waste to my flock block?
Absolutely. Chopped dried vegetables, crushed eggshells, dried herbs like oregano or cayenne pepper, and other kitchen scraps enhance nutrition and add variety. Avoid anything moldy, high-sugar processed foods, or avocado. Dried herbs also provide natural pest deterrent benefits.
What’s the difference between molasses and corn syrup for flock blocks?
Molasses provides better nutrition and a richer flavor chickens prefer, but corn syrup works as a budget alternative. Molasses binds ingredients more effectively and adds iron plus trace minerals. If using corn syrup, use slightly less as it’s thinner than molasses.
How should I hang a flock block in the coop?
Drill a hole through the center of your finished block, insert an eye hook or carabiner, and suspend it from coop rafters or fencing at about beak height for your birds. This keeps blocks off the dirty ground, extends lifespan, and provides enrichment as chickens stretch and peck.
Do flock blocks replace regular chicken feed?
No, flock blocks are treats and enrichment supplements, not complete nutrition. They should make up no more than 5-10 percent of your chickens’ daily calorie intake. Continue providing quality layer feed or grower feed as your birds’ primary nutrition source.
