Backyard Chickens: The Best Feed to Buy For Healthy ISA Brown Chickens

Updated: 01 April 2021


ISA Brown chickens make a lovely addition to your backyard chicken flock. They’re low maintenance, friendly and love a cuddle. The ISA Brown’s temperament makes them great for small children.

Plus, they’re eggceptional layers!

To keep your ladies laying lots of high-quality googs, you need to provide them with the nutrients they need to keep them fighting fit.

What do backyard chickens eat? Read my blog on the essential nutrients you should include in your backyard chickens’ diet.

Hybrid ISA Brown, Hyline Brown, and Lohmann Brown chickens are highly demanding ladies with high dietary requirements. 

Aim for feed rations of 17%, but 16% will suffice. Anything less than this, though, and you'll notice a drop in your ISA Brown’s egg quality and quantity.

The Secret To Getting ISA Brown Chickens To Lay Longer

Hybrid layer genetics are pretty remarkable. 

When you’re learning what to feed backyard chickens in Australia, you need to understand they thrive on 111g of high-quality pellets or grain ration per day, to maintain an ideal weight of 2 kg.

Having farmed ISA Brown chickens, I'll always have a soft spot for them. Their personality makes them the number one choice for open range egg farms.

On the farm, your chickens are free ranging, so they need constant access to feed. However, if you're keeping a small flock in chicken coops in your backyard, the trick to getting them to lay for longer? 

Don’t let them get fat! 

Poultry egg-spert Megg Miller told a story of a farmer who owned a 7-year-old ISA Brown chicken who still laid! This is quite remarkable, given that the egg production of most hybrid hens declines after their second year of lay. And few live beyond four years of age.

What’s the secret to this hen's egg-cellent production? She was well-fed but not over-fed, foraged daily, and maintained a healthy weight at around 2 kg.

Hi Helen, sounds like it could be a layer mash? That means it’s been crushed and can be quite fine. I would suggest feeding it as a “porridge”, and adding a little water to it. Only feed what the hens will eat in a day. So 110g each should be about right for Lohmanns. Replace daily. That way they will get all of the goodness that’s in the finer powder and no wastage. If that doesn’t work for you and your feeder, I would suggest one of the feeds above. Best, Elise

I have Lohman chooks, really beautiful and laying well, I use layer feed from the commercial farm I got them from and ‘they’ say their feed is excellent and they make it their.. but as a lot of it is fairly fine and they flick quite a bit if it from the feeder. Happy for any suggestions
Thank you
