What happens if you give chickens a large dose of vitamins?

I asked my husband to add the vitamin liquid to the chickens water. A couple days later I noticed there was a tinge to the water, caused from the vitamins, so I asked him how much did her give. He told me a cap full. Well the directions say 15 ml to 100 chickens. Well I have 20 chickens, and the main watering can holds 30 liters of water. I would imagine that a cap full is about 50 ml. So my 20 chickens should get a total of 3 ml a day. So now I have to figure out how much they drink a day. Does 2 liters sound like enough?

These last 2 days have shown a marked decrease in egg production. I was wondering if the vitamins could play a part in this.

Bad things can happen if you overdose vitamins, especially the fat soluable kinds like vitamin A. In humans at least, Hypervitaminosis A can cause liver problems, osteroporosis, and very very dry skin and hair loss.

Since their feed should already have vitamins in it, less is best.
