6 Best RFID Scales for Farms

That tattered notebook filled with smudged weights and ear tag numbers is a familiar sight on any small farm. You try to track who’s gaining and who’s falling behind, but it’s a chaotic process that often gets abandoned by mid-season. Shifting from guesswork to data-driven decisions is the single biggest step you can take to improve your flock’s health and your farm’s bottom line.

Why RFID Weighing Matters for Your Small Flock

Eyeballing an animal is a useful skill, but it’s a poor substitute for a scale. A few pounds can be the difference between a profitable market lamb and one that costs you money to keep feeding. It can also be the first sign of a health problem long before an animal looks visibly ill.

This is where RFID (Radio Frequency Identification) changes the game. By pairing an electronic ear tag (EID) with a scale, you eliminate manual recording errors and save an incredible amount of time. Instead of fumbling with a pen, a clipboard, and a struggling sheep, you simply scan the tag, and the weight is automatically recorded against that specific animal’s ID.

For a small farm, this isn’t about massive industrial efficiency. It’s about making every minute count. It means you can weigh your entire flock in the time it used to take to do a handful, giving you a complete picture of your animals’ performance. This data allows you to identify your best ewes, pull poor performers, and make culling decisions based on facts, not feelings.

Shearwell EID Weigh Crate: All-In-One Solution

If you want a plug-and-play system, the Shearwell EID Weigh Crate is your starting point. It’s a complete package: a sturdy crate to hold the animal, load bars underneath to do the weighing, and an integrated EID tag reader. You just set it up, connect an indicator, and you’re ready to go.

The biggest advantage here is simplicity and safety. The crate contains the animal securely, which reduces stress for both them and you, especially if you’re working alone. It ensures the animal stands still and centered, leading to more accurate and repeatable weights every single time.

The trade-off is cost and a lack of flexibility. A full crate system is a significant investment compared to building your own setup. It’s also a bulky piece of equipment that isn’t as easy to move around as a more modular system. Think of this as the best option for someone who values time and ease-of-use over a lower initial price tag.

Shearwell Load Bars for Custom Weighing Setups

For the farmer who already has a good handling chute or likes a DIY project, load bars are the core component of a weighing system. These are simply the sensors that measure the weight. You place them under a platform of your own making, turning any part of your alleyway into a scale.

This approach offers maximum flexibility. You can build a lightweight aluminum platform for portability or a heavy-duty wooden one that lives permanently in your barn’s race. Because you’re providing the platform and restraints, the initial cost is significantly lower than a full weigh crate.

However, this flexibility comes with responsibility. The accuracy of your scale depends entirely on how well you build and level your platform. An unstable or poorly constructed platform will give you inconsistent readings, defeating the whole purpose of collecting data. This is the ideal path if you’re on a tighter budget and are confident in your ability to build a solid, reliable setup.

SDL440S EID Stick Reader for Mobile Data Capture

The stick reader is the magic wand that connects your animal to your data. While some weigh crates have built-in readers, a handheld stick reader like the SDL440S provides incredible mobility. It reads the animal’s EID tag with a quick wave and sends that ID to the weigh indicator via Bluetooth.

Its real power is revealed when you’re not weighing. You can walk through the pasture and scan a ewe to bring up her history on your indicator. You can record treatments, make notes about mothering ability, or mark an animal for culling, all right there in the field.

This tool fundamentally changes how you interact with your records. Instead of being tied to a computer or a notebook at the barn, your flock’s data is in your hand wherever you are. It bridges the gap between the physical animal and its digital record, making data management a dynamic, on-the-go process.

EziWeigh 7i Indicator for In-Paddock Analytics

The weigh indicator is the brain of the operation, and the EziWeigh 7i is a powerful one for small-scale producers. It does more than just display the current weight. It connects to your EID reader and load bars, instantly linking the weight to the specific animal and storing the record.

Its most useful feature is the ability to display key information right on the screen. When you weigh a lamb, it can immediately show you its Average Daily Gain (ADG) since the last weigh-in. This instant feedback is a game-changer. You no longer have to wait to get back to a spreadsheet to see who your star performers are.

This capability allows you to make decisions on the spot. Is a lamb’s gain falling off? You can decide to pull it for extra feed or deworming right then and there. The EziWeigh 7i turns weighing from a simple data collection task into an active management tool.

Shearwell Auto Drafter for Efficient Sorting

An auto drafter might sound like overkill for a small farm, but it’s a logical next step when your flock grows beyond a couple dozen head. This unit integrates directly with your EID reader and weigh indicator to sort animals automatically based on pre-set criteria. It’s the ultimate labor-saving device.

Imagine you need to sort your lambs into three groups: market-ready, keep-feeding, and a watch list. You set the weight parameters in your indicator. As each lamb walks across the scale, the system reads its tag, checks its weight, and automatically opens the correct gate to sort it into the right pen.

This isn’t a day-one purchase. But if you find that sorting animals is becoming a major bottleneck that requires multiple people and creates a lot of stress, an auto drafter can be a transformative investment. It turns a chaotic, multi-hour job into a smooth, one-person operation.

Shearwell Portable Alleyway Platform Weighing

If a full crate is too much and building your own platform seems daunting, a portable alleyway platform is the perfect middle ground. This is a pre-fabricated, durable platform with load bars already installed. You simply drop it into your existing race or alleyway.

This option is faster for weighing a group of animals that are accustomed to moving through a chute. They walk on, pause for a second to be scanned and weighed, and walk off. It’s less confining than a crate, which can speed up the process and reduce stress on calmer animals.

The main consideration is that it relies on your existing handling system to control the animals. If your alleyway is wide or your sheep are unruly, you may struggle to get them to stand still long enough for an accurate reading. It’s an excellent, efficient choice for farms that already have a well-designed handling setup.

FarmWorks Software: Tying Your Data Together

All this hardware is great for collecting data, but its true value is unlocked when you can see the big picture. FarmWorks by Shearwell is the software that brings all your records together. It takes the data from your weigh indicator and turns it into powerful, easy-to-understand reports.

This is where you move beyond individual weights to flock-level analysis. You can compare the performance of lambs from different sires or see which ewes consistently produce the fastest-growing offspring. You can track medication usage, manage breeding cycles, and generate reports for sales or certifications with a few clicks.

Without software, your EID system is just a fancy digital notebook. With it, you have a comprehensive farm management tool. It’s the final step that transforms raw data into actionable intelligence, allowing you to make smarter, more profitable decisions for your farm’s future.

Investing in an RFID weighing system is about buying back your time and replacing uncertainty with knowledge. You don’t need to get everything at once; start with load bars and an indicator, then build from there. The goal is to make informed choices that improve your animals and your peace of mind.
