Poultry Vaccination & Every Dose, on Its Date
Protects broilers
Enter your day-old-chick arrival date and get the exact calendar date and route for every vaccine — Marek's, Lasota, IBD and boosters — so no dose is missed.

One arrival date sets every vaccine date
Chicks are vaccinated on a fixed age-in-days schedule, not on a whim: Marek's goes in at hatch on day 0, an early Lasota/NDV dose follows, IBD/Gumboro and boosters come after, and R2B sits later in the program. Because each dose is tied to the bird's age, the only thing you really need to know is the day the day-old chicks arrived — from there every dose has a calendar date. Hit those dates with the right route and the flock is protected before disease ever finds it.
This tool turns the arrival date into a dated plan: it gives the number of vaccinations, each vaccine's date, the route for every dose, and the last dose date. Use it to set reminders, brief whoever does the vaccinating, and keep timing and route correct — the two things that decide whether a vaccine actually protects. Pair it with the Poultry Brooding and Broiler Profit tools to run the whole batch on schedule.

Frequently Asked Questions
What is a poultry vaccination schedule?+
It is a fixed plan of which vaccines a flock gets and at what age, measured in days from the day the chicks hatch or arrive. Because the schedule is age-based, once you fix the day-old-chick date every dose — Marek's, Lasota/NDV, IBD/Gumboro, boosters and R2B — lands on a definite calendar date, so nothing is forgotten and protection builds in the right order.
How does the calculator work out the dates?+
Each vaccine has a target age in days (for example Marek's at day 0, an early Lasota/NDV dose, IBD/Gumboro a little later, then boosters and R2B further out). The tool adds those day offsets to your arrival date to produce the calendar date for every dose, the route for each, and the date of the final dose.
Why is Marek's given on day 0?+
Marek's disease vaccine is given at the hatchery on the day of hatch — day 0 — because the chick must be protected before it is ever exposed to the virus, which is widespread and spreads through dander and dust. Vaccinating later, after exposure, is far less effective, so it is the first dose on every schedule.
What are the main poultry vaccines and routes?+
Common ones are Marek's (injection at hatch), Lasota/NDV against Newcastle disease (eye-drop or drinking water), IBD/Gumboro against infectious bursal disease (eye-drop or water), Newcastle boosters, and R2B/Mukteswar as a later Newcastle booster (often by injection). The route — eye-drop, drinking water or injection — matters as much as the timing.
Does timing really matter that much?+
Yes. A vaccine given too early can be blocked by maternal antibodies the chick still carries; given too late, the bird may meet the field virus before it is protected. The age-in-days windows on the schedule are chosen to thread that gap, which is why hitting the calendar dates the tool gives is so important.
Why does the route of administration matter?+
Each vaccine is designed for a route. Eye-drop puts live virus where local immunity is needed and gives an even dose per bird; drinking-water vaccination is fast for big flocks but needs clean, chlorine-free water and thirsty birds so every chick drinks enough; injection is used for Marek's and some boosters. Wrong route or technique means poor or no protection.
Is the schedule the same for broilers and layers?+
The early doses overlap, but layers live far longer and get more boosters and extra vaccines over their laying life, while broilers finish in a few weeks and need only the early program. Enter your flock type or adjust the schedule accordingly — the day-old date still anchors every date the tool produces.
What if I miss a vaccination date?+
Give the missed dose as soon as you notice rather than skipping it, and keep the rest of the schedule on its original dates if possible. A late dose is better than none, but repeated gaps leave windows where disease can hit, so use the calendar the tool gives to set reminders ahead of each date.
Does this replace a vet's advice?+
No. It turns a standard age-based schedule into dated reminders for planning, but the exact vaccines, strains and boosters depend on your region's disease pressure and your birds. Confirm the program with a poultry vet or your vaccine supplier, then use the dates here to stay on track.
Does it work for any flock size or date?+
Yes — the dates depend only on the arrival date and each vaccine's age in days, so it works for ten chicks or ten thousand, broiler or layer, any start date. It runs entirely in your browser; nothing about your flock is uploaded anywhere.
