About Kalmbach Feeds Henhouse Reserve

A Full Line of Poultry Feeds

Kalmbach makes feeds for every bird in your flock, from the moment they hatch to the time they mature. They offer over 50 different poultry products tailored for each of your birds, making them a one-stop-shop for all your chicken feed needs.

Quality. Consistency. Kalmbach.

Kalmbach takes pride in producing a quality product, every time. That’s why their feeds are fixed formulated, to ensure you get the exact same feed every time you open a bag!

Your Flock Will Squawk!

Henhouse Reserve is crafted with real, wholesome vegetables, grains you can actually see, plus nutritious pellets that provide the perfect combination of protein, vitamins and minerals. But the best part is that Henhouse Reserve is rooster-approved, so there’s no need to feed the gentlemen something different. Your whole flock will love it!

Preferred Over Traditional Pellets

Chickens tend to prefer Henhouse Reserve over traditional layer pellets. Once you start feeding it, your flock will want nothing less. Fully fortified with vitamins, minerals and amino acids to produce strong eggshells and wholesome, tasty eggs, its 17% protein content lets you rest assured knowing your hens are getting everything they need.

Proprietary Blends

Henhouse Reserve contains LifeGuard and YolkGuard proprietary blends to boost your birds’ health and yield beautiful, vibrant eggs.

LifeGuard

LifeGuard is an all-natural, proprietary blend of prebiotics, probiotics, essential oils and digestive enzymes. It helps introduce and nurture beneficial bacteria in the gut to maximize intestinal health, and the specially selected essential oils help reduce stress and support healthy immunity.

YolkProud

Poultry owners take pride in their egg quality, and one healthy egg indicator is the color of the yolk. That’s why they call this blend YolkProud—this natural blend of flower and vegetable extracts can help you get the beautiful, vibrant egg yolks you want, for the ultimate source of pride!

Questions & Answers

4 Customer Questions

Where do the ingredients come from in this product?

Answer by Chewy • Jan 30, 2023
Kalmbach Feeds sources their major grain and protein sources from as many local farmers in Ohio as they can.

Should you just leave the block for free access whenever they want or should you put it out on a schedule?

Answer by Chewy • Dec 01, 2025
The block can be left, so hens can have free access.

How do you feed this block? Just on the ground?

Answer by Chewy • May 01, 2025
You can place the Henhouse Reserve Supplement Block directly on the ground. You can also set it on a dry, elevated surface like a brick, block, or inside a feeder tray to keep it off wet or muddy ground. If possible, place it under cover (like in a coop or run with a roof) to protect it from rain and help it last longer.

Is this an okay treat for ducks and geese?

Answer by Chewy • May 17, 2022
This supplement block is designed for multiple poultry species and can be fed in conjunction with a balanced complete feed for poultry 14 weeks and older.

My chickens have been working on this block since I hung it up. One more item to prevent boredom. I also have the pumpkin block hanging and they are eating that one as well. Block are compressed so they don’t fall apart but break apart nicely when chickens are pecking at it.

Very heavy

At first they didn’t know what to do with it, but then they realized it was food. But the corn my girls don’t eat any of the corn.

Chickens do not like it

I got this for my chickens for not only a treat but to give them something to do.. They completely ignore it. Oh well, can’t please everyone!

Great concept- unfortunately my chickens don’t care for it

I placed it in the coop and the chickens pay no interest to it. I’ve moved it around and they just don’t seem to care at all for it. It wasn’t cheap so I’m leaving

I placed it in the coop and the chickens pay no interest to it. I’ve moved it around and they just don’t seem to care at all for it. It wasn’t cheap so I’m leaving it there hoping one day they peck at it but they haven’t and it’s been three weeks today and still nothing. Maybe my chickens are just picky?

I had high hopes ..

I thought surely my chickens would love this supplemental treat block to peck at, but unfortunately they weren’t interested in it whatsoever. .. even after I chipped

I thought surely my chickens would love this supplemental treat block to peck at, but unfortunately they weren’t interested in it whatsoever. .. even after I chipped off some of the sides to encourage them. Total bummer/waste of money for us.

It was the same as their feed

Within a couple days of the block being in their run I started getting more eggs.

Too hard.

This looks great but it is too hard for my girls. Eventually my husband too it apart with a saw and a drill. Now I soak the pieces overnight before feeding it to

This looks great but it is too hard for my girls. Eventually my husband too it apart with a saw and a drill. Now I soak the pieces overnight before feeding it to them the next day. They do love it but it’s not what I had in mind when I ordered it.

Did not stand up to wet fall weather

Chickens enjoyed the block. Ate it faster than other brands. Only complaint is that we had a few cold, rainy days and the block disintegrated.

My chickens love these blocks.

It is so easy to use if we are going to be traveling and wan too make sure they have extra food in their coop.
