01
TURMERIC
IF YOU WANT AN ACTIVE FLOCK, GIVE TURMERIC.
Shorter days and cold mornings keep her immune system busy. Turmeric contains curcumin, a compound researched in poultry nutrition for antioxidant status and immune response. It is already measured into every capful.
Supports normal immune function
Contains natural curcumin
Studied in poultry nutrition
No spice-cupboard guesswork
02
OREGANO OIL
IF YOU WANT FIRM DROPPINGS, GIVE OREGANO OIL.
Runny droppings are usually the first place you see her gut is off. Oregano oil contains carvacrol and thymol, natural plant compounds that support a balanced gut and healthy digestion.
Supports healthy digestion
Helps keep droppings firm
Contains carvacrol and thymol
No droppers, no measuring
03
OMEGA-3
IF YOU WANT ORANGE YOLKS, GIVE OMEGA-3.
Pale yolks often come down to what is missing from her diet. Our omega-3 comes from flaxseed, not fish, and supports healthy laying and the nutritional value of her eggs, for richer, deeper-colored yolks.
Flaxseed-sourced omega-3
Supports richer yolks
Supports healthy laying
Adds omega-3s to her diet
04
VITAMINS D3 & E
IF YOU WANT STRONG SHELLS, GIVE VITAMIN D3.
Thin shells usually mean she is not using her calcium well. Vitamin D3 helps her absorb and use the calcium she eats for shells and bones, and vitamin E supports a healthy immune system. Both come in the same bottle.
Supports strong shells
Helps her use dietary calcium
Supports healthy bones
Vitamin E for immune health
YOU COULD BUY EACH ONE SEPARATELY AND MIX IT YOURSELF.
Four bottles off the shelf, a measuring spoon and your best guess at the doses, hoping you are not overdoing one thing and underdoing another. Or one capful of Roosty’s Immunity Booster in her water.

DAILY ROUTINE
JUST ADD IT TO HER WATER.
Every chicken drinks, so every chicken gets some. One capful (1 oz) in every 2 gallons of drinking water, every day. No changing her feed, no extra bowl, no measuring spoons. Already using Flock Armor? Different job: Flock Armor is a dry herb mix for her feed, Immunity Booster is a liquid for her water. Plenty of keepers use both.
1 oz per 2 gallons, daily
Safe for chicks, ducks and other poultry
Keep collecting eggs as normal

Quality, natural ingredients which is what you want since we eat the eggs. The cap holds about the amount you need per gallon of water which is handy. And I swear the chickens drink more with this additive in there, they seem to like it.
