Shelf Life of my Emergency Kit Stash

[Tumbleweed Farm]

I have the following in my chicken meds crate and some are about 2 yrs old now. Do they have a shelf life?

Valbazen
Wazine
Corid
Rooster Booster
Invermectin
Selium and Vitamin E paste (for goats)

I rarely have to use any of this stuff, knock on wood but I'm raising a bunch of new babies and hope I don't have to go buy new.

Thanks!

Each drug will have an expiration date on the package. Most drugs that I have seen at my feed store have an expiration date approximately 12-18 months. I would use some drugs past expiration date until I could get fresh ones, but that is something you would have to decide for yourself.
