No.
Follow the directions for the medication that you purchased.
There is a Tylan for putting in water, but you have to specifically buy that type. It comes as a powder for mixing into the water.
If you are not sure what you are treating for:
tell all of the very specific symptoms to people by- contacting a vet, check with experienced people on the emergency thread on this board, search for a good website about poultry, or buy The Poultry Health Handbook or another book with symptoms and treatment suggestions....
please don't randomly treat with antibiotics.
Hope you find what is going wrong.
