I ordered my 7 chicks yesterday. I did check the box to have them vaccinated for Mareks. Are there any other vaccines I should give? We are in a pretty suburban area, but back up to a drainage ditch and retention pond. The neighbors have ducks, we get a handful of other types of water birds and all the typical wild birds. We have raccoons and opossum, hawks and owls. I am hoping to free range several times a week for a short period. Nobody in the family comes in contact with other chickens....... Thanks!!
