5 Reasons Your Girls Need

Immunity Booster

Before the Hard Freeze

Not sick. Just not themselves. Paler combs, less foraging, a quieter nest box. Here are the five reasons I tell keepers to add a capful to their water before the hard freeze, not after.

Complete Immune & Gut Support in One Daily Capful


Pale combs, runny droppings and a quiet nest box are often the first signs a hen is running low. Immunity Booster covers what she needs every day, right in her water.
One capful per gallon. No catching hens, no pills, nothing to mix into feed.

A Visible Bounce-Back Keepers Can See


Keepers tell me the change shows at feed time first: more energy, combs with color again, and more eggs in the box than the week before.
In our September 2025 survey of 134 customers, 96% said they'd recommend Roosty's. Immunity Booster holds 4.8 stars from 420 reviews.
3.

Four Natural Ingredients, Double Concentrated

Flaxseed omega-3, oregano oil, turmeric and vitamins D3, D and E, measured into one capful. No guessing at amounts like you do with vinegar or garlic water. Made in New Mexico with US-sourced ingredients.
4.

You Keep Every Egg. Safe for the Whole Flock.

Immunity Booster is non-medicated, so there's no egg withdrawal. Collect the eggs and eat them the same morning.
Chicks, ducks, geese, turkeys and quail can have it too.

Brighter Combs in Weeks, Not Months

Most keepers see their girls drinking more in week one, then brighter combs and more energy within two to four weeks. Start before the hard freeze, not after.
Give it 90 days. If you don't see a difference, you get a full refund.
