How long do I use nutri-drench

[LeastinID]

We're wrapping up a Corid regimen.
Because Corid is s'pozed to deplete B vitamins (?) we're advised to start giving our chickens Nutri-drench.
How long are we s'pozed do use Nutri-drench?

You can give any kind or brand of chicken vitamins for a few days after Corid is completed. 3-5 days would be good. NutriDrench can be given orally 1 ml for every 3 pounds of weight, or in the water. There are also powder vitamins at your feed store for poultry to add to the water.
