Flock Supplements & Herbs FAQs

Do chickens need supplements if they eat layer feed?
A quality layer feed covers most nutritional bases, but a few supplements are still worth adding. Grit is essential for birds without access to pasture — they need it to grind food in their gizzard. Oyster shell provides extra calcium for strong eggshells and should be offered free-choice alongside layer feed. Probiotics can support gut health, especially after illness or antibiotic treatment.

What is grit and do my chickens need it?
Grit is small stones or crushed granite that chickens swallow and store in their gizzard to grind up food. Chickens that free-range on soil naturally pick up grit, but confined birds need it offered separately. Without grit, chickens can't properly digest whole grains, seeds, or fibrous treats. Offer insoluble grit free-choice at all times.

What herbs are good for chickens?
Many herbs have natural benefits for backyard flocks. Lavender and mint are calming and help repel insects in the coop. Oregano has natural antimicrobial properties. Calendula supports immune health and adds color to egg yolks. Nesting herbs blends — like those from Roosty's — combine several herbs to freshen nesting boxes and support hen wellness naturally.

When should I give my flock electrolytes?
Electrolytes are most useful during heat stress, illness, shipping stress, or after antibiotic treatment. Add a poultry electrolyte blend to drinking water for 2–3 days during hot weather or recovery periods. Don't use them as a permanent water additive — plain fresh water should always be available alongside any supplemented water.

Are herbal supplements a replacement for veterinary medicine?
No — herbs and natural supplements support general wellness but are not a substitute for treatment when birds are sick. If you suspect illness, isolate the bird and assess symptoms. For serious conditions like coccidiosis, respiratory infection, or worm infestation, use appropriate veterinary-grade treatments. Herbs work best as a preventive and wellness tool, not a cure.
