Hi Guys, What age is the youngest you can vaccinate a bird? I have a team of late breds now all ready to be jabbed up. But I also have 3 birds just left the nest 7-10 days go. Want to do them all at the same time, but not sure what age might be, "too young" to get em done. Also is the gear you use the same stuff for old birds as it is young birds? Any info much appreciated. Cheers, Pete
