Abstract: The present invention provides in ovo injection devices, including a novel vaccine/substance conservation valve (VCV), a needle depth adjuster (NDA), and methods for selectively delivering vaccines and other substances to eggs in the context of poultry hatcheries. The valve of the present invention allows for the conditional dispensing of vaccines and other substances dependent upon the presence or absence of an egg. When an egg is present, the valve becomes activated, allowing vaccines or other substances to be injected. When an egg is absent, the valve is not activated, thus vaccines and other valuable substances are conserved. The NDA allows embryonated eggs to be more safely injected by reducing the depth of needle penetration, particularly in smaller eggs.
