Hey all, so we plan to vaccinate for Marek's soon and had something cross my mind. I was wondering what the protocol is for vaccinating incubator chicks. If the first ones hatch on one day and the rest follow on another, when do you vaccinate? Is it fine to just vaccinate after they have all hatched and when I go to put them in the brooder, or pull them as they hatch? Any tips from the experienced is much appreciated as well, thanks!
