Except - it's not the chickens who attract rats - it's the grain. So it wasn't surprising that I ended up with a huge rodent problem.
I did my research, which told me the time for providing grain-fests for rodents had to end. Rats can bring disease to the chicken house, not to mention to your family.
I decided there and then that first I had to get rid of the rats, and then I had to solve the problem long term. The open feeders had to go.
So I invested in two things: an electronic rat trap and a Grandpa's feeder. And I have never looked back.
Not had one single, solitary rat since.
It's basically any type of feeder which leaves even a small amount of grain exposed. It doesn't have to be much - rats and mice can squeeze into the tiniest of holes.
Some of the more recent designs for small flocks have a bucket or pipe, with openings at the bottom for chickens to peck from.
Some are designed so that the chicken has to put its head inside, some are a tray. They all look good - but they're an open invitation to rodents.
A kind of rat-Donald's.
The one I used to have was like this one (mine had a lid). It's common to many backyard chicken keepers.
Made of galvanised steel, the feed goes into a round container and comes out in a pan at the bottom. As the chickens eat, the grain refills from the container. It can keep several chickens fed for several days.
But, even when I hung it off the ground, mice and rats managed to get inside. They can get through the tiniest of holes. And they can jump.
I opened the lid one morning to find a rat looking up at me from inside the drum. It was having its own private grain-fest.
It was time for a change.
I did my research. The way to keep rodents and wild birds - who can bring disease to your flock - out of feeders is to have one that's completely enclosed. Grandpa's fitted the bill.
It's been on the market for over 20 years - I got mine at a point where I had to order it from New Zealand! Now, thankfully, they sell via Amazon.
It's waterproof, rodent-proof and predator-proof. In my view, it's the best on the market.

The top of the hopper has a lid, and its edges cover over the sides of the feeder. The front and back are held securely with pins which slot into holes on the feeder itself.
Some animals - raccoons, for example - are adept at picking locks to get into the chicken run. They won't, though, get into this.
It also makes sure the top can't blow off and leave grain exposed to either rodents or to rain - both of them sure ways to bring disease to the chicken house.
It's a simple concept. The chicken(s) stand on the treadle platform at the front. A lever system works to raise the lid of the grain tray. The chicken eats...
...and steps back off the platform. The lid closes until the next chicken arrives.
The hopper has a sloped back, so there's never any grain stuck - it just naturally falls down into the feeding box.
There's an anti-scratch bar inside, which stops the hens standing in the grain and scratching about, as they like to do. And there are side panels, which also prevents grain flopping over the side. Great addition - based on feedback from customers.
So no grain goes on the ground. Don't you just love a company that listens?
Well, my little Lemon Millefleur Sablepoot, Bono, thinks so!
Here he is, taking his turn while one of my Light Sussex hens stands in line behind.
You may have to start by putting a weight on the treadle to help bantams open the lid. Bono originally waited until other hens were on the treadle and stepped up beside them, but eventually he got the hang of opening it by himself.
Nothing. But the weight needed to open it is more than the weight of anything but a mega-mouse. And the hopper is far enough away from the platform that rodents couldn't get to the grain and keep their weight on the platform to hold the lid open.
I've never seen any evidence that any rodent has managed to get inside this feeder. No droppings, no rat staring up at me - nothing.
It's built like an anti-rodent Alcatraz.
This is probably the thing that most people ask me. The answer is "no". The chickens just move their head out of the way instinctively, before it closes on them.
I've used this for over 5 years now with a flock of 20+ chickens. Not one of them has been hurt, not even when they use it to do acrobatics (yes, the hen inside the grain tray survived!).
It's all in the quality. The materials and the design together make this a feeder to last. It's waterproof, there are no plastic or wooden parts for rodents to gnaw their way through.
The manufacturers are so confident of the quality that they offer a two year "total satisfaction" guarantee. Money refunded, no questions asked.
You really cannot say fairer than that.
Yes, there are similarly-designed feeders on the market which cost less. But be careful. They're nothing like as well made. Grandpa's uses galvanised steel, while the imitations are Chinese imports using lightweight aluminium - cheap materials which won't last anything like as long.
Take a look at their pictures and compare the mechanism with Grandpa's. The "alternative feeders" are not as well designed.
The choice is yours, of course. If you really can't afford a Grandpa's, then they're better than nothing. In the long run, though, you get what you pay for.
If you've read any of my other product reviews, you'll know that I have a "Golden Egg Award" where one egg means don't go near this product, and five means get out there now and buy it!
I genuinely only recommend products that I have bought myself and love, or that someone I know and trust has and loves.
In the case of Grandpa's feeders, I have no hesitation recommending. I love it. My flock loves it. That's good enough for me.
