Hi! My name is Dr. Henley – A licensed veterinarian specialising in chicken health for over 14 years.

Chicken keeping is hard. Really hard.

One day your girls can look healthy…

The next? Lethargic, lay barely any eggs, and dropping soft, brittle eggs that crack before you can even collect them.

#1 Hidden Cause of Flock Health and Egg Problems

Hi! My name is Dr. Henley – A licensed veterinarian specialising in chicken health for over 14 years.

Chicken keeping is hard. Really hard.

One day your girls can look healthy…

The next? Lethargic, lay barely any eggs, and dropping soft, brittle eggs that crack before you can even collect them.

Here’s What My Patients Use To Actually Keep Calcium Levels High:

In chickens, there’s one critical nutrient that controls everything: Bioavailable Calcium.

When calcium levels are optimal, your flock thrives — delivering rock-hard eggshells, rich golden yolks, strong leg bones, and rapid molt recovery.

When hens are deficient, their bodies are forced to leech calcium directly from their own bones just to form a single eggshell.

Studies show over 70% of laying hens suffer from silent calcium depletion during peak laying seasons or molting cycles.

By the time you notice soft-shelled eggs, rubbery shells, or feather plucking, your hens have already been running on empty for weeks.

And peak laying season combined with warm weather makes this strain even worse. Without quick intervention, egg production plummets.

Most standard approaches simply don't cut it:

❌ Crushed Oyster Shells — Heavy and slow to digest; hens often ignore the large grit pieces.
❌ Standard Feeds — Contain baseline calcium, but lack the high-fat and protein vehicles needed for fast absorption.
❌ Traditional Dried Mealworms — High in protein, but severely calcium-deficient with an inverted calcium-to-phosphorus ratio.
❌ Synthetic Calcium Drops — Messy to dose, hard to mix evenly in water, and easily wasted.

You need to deliver high-density calcium alongside the essential protein and healthy fats required for maximum bioabsorption.

Luckily, there is one simple, 100% natural feed addition you can give to your precious hens right now…

Here’s What I Recommend To My Patients:

PureGrubs Black Soldier Fly Larvae — after 14 years, I realized this is the single best natural superfood to support hen calcium levels, feather strength, and daily egg production. Here’s why:

It delivers 85x more natural calcium than standard mealworms, giving hens the exact building blocks required for rock-hard, thick eggshells.

It features an optimal 2:1 calcium-to-phosphorus ratio, ensuring the calcium is actually absorbed into their system rather than passed as waste.

High levels of digestible crude protein (40%+) and healthy fats fuel fast molt recovery, rebuild feather coverage, and keep laying energy high.

PureGrubs is 100% natural, vet-recommended, and loved by thousands of flock owners who demand clean, sustainable nutrition.

And the best part? Zero chemical additives. You get pure, farm-fresh, nutrient-dense eggs every single day.

“My girls’ shells used to crack just from picking them up! After two weeks on PureGrubs, we’re getting thick, heavy shells and rich orange yolks daily.” — Robyn E.

"I had three hens going through a brutal molt—feathers everywhere and completely stopped laying. Added PureGrubs to their routine and within days their energy was back. Now their coats are glossy, full, and the egg basket is full again!” — Sarah W.

High-density bioavailable calcium begins restoring your hens' internal reserves. You’ll notice an immediate boost in daily foraging energy and active behavior around the coop.

Soft, rubbery, or thin eggshells begin to firm up rapidly. The balanced 2:1 calcium-to-phosphorus ratio ensures nutrients are being absorbed effectively, laying the foundation for stronger shells.

2 week

4 week

Instead of empty nesting boxes or cracked eggs, you’ll collect heavy, thick-shelled eggs with noticeably richer, golden-orange yolks. Egg production consistency picks up across the entire flock.

The 40%+ crude protein content accelerates feather regeneration. Bare spots from molting or feather pecking fill in with dense, glossy plumage, while bone strength is fully safeguarded.

2 Month

3 Month

Peak egg quality and flock vitality are fully sustained. Your hens stay vibrant, energetic, and fully feathered year-round without suffering from calcium depletion—making flock keeping an absolute joy again.

Here Are 7 Signs Your Chickens’ Health Is In Trouble:

If your chickens have any of these signs, you should start prevention as soon as possible:

❌ Soft, rubbery, or paper-thin eggshells

❌ Sudden drop in daily egg production
❌ Hens eating their own eggs
❌ Slow feather regrowing or bare patches during molting
❌ Feather pecking and bullying among flock mates
❌ Weak, shaky legs or reluctance to walk
❌ Pale combs and low overall energy

It will get worse. But you can prevent it before it’s too late.

You’re doing everything: buying extra oyster shells, mixing in feed additives, offering kitchen scraps, and setting up heat lamps.
