What's really costing you money every flock?
High Mortality
Losing birds in the first week can cost an estimated $0.30-0.50 per bird. Multiply that by 25,000+ head and it adds up fast — straight off your settlement.
Poor Feed Conversion
When gut health suffers, birds eat more but gain less. A 0.05 FCR improvement on a 20,000-bird house can save an estimated $600-1,200 per flock.
Antibiotic Dependence
Retailers and integrators are pushing NAE programs harder every year. You need alternatives that actually perform, not just check a box.
How It Works
| Feature | What It Means for You |
|---|---|
| Multi-strain probiotic blend | Colonizes the gut with 7 beneficial bacteria strains that crowd out pathogens like E. coli and Salmonella |
| Water-line delivery | No handling stress, no extra labor — runs through your existing medicator or proportioner |
| Day-one dosing protocol | Early colonization gives chicks a competitive advantage before harmful bacteria establish |
| Shelf-stable formulation | No refrigeration required — store at room temperature for up to 18 months |
| USDA Organic compliant | Approved for use in certified organic operations — no withdrawal period |
| Compatible with chlorinated water | Engineered to survive standard water treatment levels up to 3 ppm chlorine |
Application: Water line (medicator or proportioner)
Standard protocol (broilers): • Days 1-3: 1 oz per 100 gallons (heavy dose for gut colonization) • Days 4-14: 0.5 oz per 100 gallons (maintenance) • Day 15+: 0.5 oz per 100 gallons every 3rd day Layers / Turkeys: • First 14 days: 1 oz per 100 gallons daily • Maintenance: 0.5 oz per 100 gallons 2x/week Stress events (heat, transport, vaccination): • Return to heavy dose for 3 days
Calculate Exact Quantity for My AreaWhy Gut Health Matters in Commercial Poultry
The broiler gut is where profit is made or lost. A healthy microbiome means better nutrient absorption, stronger immune response, and fewer losses to enteric disease. Big Ole Bird establishes beneficial bacteria from day one, giving your birds a competitive advantage before pathogenic bacteria can colonize.
Unlike antibiotics that kill indiscriminately, probiotics work by competitive exclusion — beneficial bacteria occupy binding sites in the gut lining, leaving no room for harmful organisms like E. coli, Clostridium, and Salmonella.
The Science Behind the Settlement Check
In a 2019 University of Georgia field trial, houses treated with Big Ole Bird showed:
- 6.2% reduction in mortality vs. untreated control houses
- 0.04-point FCR improvement (translating to ~$600-1,200 savings per 20,000-bird house per flock)
- Reduced veterinary intervention for enteric issues
These aren’t lab results — they’re from commercial broiler houses under real production conditions.
Built for the Way You Farm
Big Ole Bird is designed for commercial-scale operations. It runs through your existing water-line system with zero additional labor. The shelf-stable formula doesn’t need refrigeration, and it’s compatible with standard water treatment up to 3 ppm chlorine.
Whether you’re running conventional or NAE programs, Big Ole Bird fits. It’s USDA Organic compliant with no withdrawal period, making it one of the few performance tools available to certified organic producers.

Cost per Bird
We started Big Ole Bird on a trial house and within two flocks, our mortality was down 4 points. Now it's on every house. The ROI isn't even close — it pays for itself by day 7.
I was skeptical about probiotics until I saw the numbers. Our FCR improved and we're spending less on gut-related treatments. Allen walked me through the whole setup.

Best Product For Chickens
Best product out there. My chickens don't molt as bad as others in my area, they lay when everyone else's chickens stop. Just wish you hadn't jacked the price so high. I used to buy the 2.5 gallon and can't put that much out at one time now. But, I'll keep buying the gallon jugs for sure.
Southland Organics replied
Thanks for the awesome review and for being a long-time customer! We're thrilled Big Ole Bird is keeping your chickens happy and healthy, and that they handle molting well. Sorry that the price change has impacted you negatively. We kept our prices the same for over ten years (2009 to 2023!) but unfortunately, inflation caught up to us. Thanks for your feedback. I appreciate your understanding and hope we can keep your business despite this change!
Too soon to tell how the product is affecting my flock. I removed a star because the jug is awful. It leaks and it is very hard to pour any out without spilling, wasting even more.
Southland Organics replied
Hey Dawn! Thanks so much for sharing your experience with Big Ole Bird so far. Do let us know what you think after you've used it on your flock for a while. I apologize for the inconvenience caused by the jug. We have vented caps that prevent the jugs from becoming swollen as the biology in the product lets off gas. When the jugs are handled roughly during shipping, product can come out of the vent, which sounds like it may have been the case in this situation. We hope to improve upon this in the future. In the meantime, we do have measuring cups that you can add to your order that are pretty helpful when measuring product. Sorry again for the inconvenience, and thanks so much for this feedback! It really helps us improve.

First time user
Midway through my first flock birds look bigger healthy mortality is down to 1/2 per thousand so far so good
Absolute snake oil
The only difference that I saw after buying this product was in my checkbook. I had the worst eneritus that I have had in years. I’ve never had much faith in copper sulphate but that did help. BOB is junk.
Big old bird
I love this product. My birds are very healthy birds.
Good stuff!
I really like this product especially for my peafowl, the babies seem to do much better when I use this stuff, I also give it to my other poultry and pigeons. Well worth getting yourself a bottle.
My chickens love it.
This is an easy to use product.
Outstanding product
We've only been using this product for 3 weeks but we can already see the difference in this batch of chicks. The size of the chicks are definitely larger than previous birds were at 3 weeks.
Big OBirds
So far so good. Birds like to drink this product.
Robust Flock
I have been using this product for over a year. I am very happy with the product and the outcome with my flock.
Big ole bird
It's a great easy to use product
Still testing
I have faith that this product will work for me. I have not had a full grow out using BOB, catalyst and MotherLoad during the same flock. I have used BOB and MotherLoad in previous flocks and performed well.
Great stuff
Great chics do so much better
Second bottle !
This is a great product! I’ve had a few valuable birds get sick and along with conventional medicine I give this to repopulate a healthy gut ! I’m also combining with a liquid vitamin and spraying on feed for my 53 turkeys since they’re suspicious of water with any color lol !
Bob
It works great the birds live it.
Top Notch company.
A company that stands behind their product. went over and above to help me with border issues in New Zealand, providing me with all the documentation etc.
Polish and Silkies
I run a small rescue and also work with local 4H and FFA groups. I breed Polish and Silkies and have a menagerie of breeds come in the rescue. I started using the B.O.B. about a year ago, and I just had to let you guys know how amazing it is. Not only does it make a huge difference in our rescues rehab but the members of the clubs that show and have started using B.O.B. at my recommendation are always placing higher at shows than those that dont. The entire livestock poultry club have now been 'converted' to believers and now use it with their flocks as well. It's a staple here, just as common as a bag of feed. Read more
