I want to vaccinate my silkies against Mareks. I have a variety of ages of chicks from 6 weeks to 1 week. I am going to have another round hatching in a few weeks. I plan to do them all at once. Wondering if anyone with experience can tell me where to get supplies and roughly what your process is? I guess I will contact the local 4H club to see if they anyone who can help. Would love any other ideas any one has... I am an RN, so I'm not at all worried about giving shots. I have just never given them to chickens!
