Question re vaccinating older chickens for Marek's

[Eggsoteric]

Where is the best (easiest) place to vaccinate older chickens for Marek's: sub-q to the back of the neck or IM (or is it still sub-q) in the leg? I've read thru a number of threads until I'm blue in the face and I'm still confused as to vaccination site.

Thanks.

most chicks are vaccinated right after they hatch. not sure why your vaccinating adult birds. I have a book that says sub-q for day olds, imagine it would be the same for adults

I ended up going with sub-q to the back of the neck. Thanks.
