You can add it with the cider I do.Garlic is a no no for chicken. A little doesn't kill them but it is cumlative. So I would lay off garlic and onion. Use the oregno and rosemary instead. Pam
I guess we have differing opinions on garlic. I got my information here: https://www.backyardchickens.com/t/386310/garlic-for-chickens
I feel like my chickens did really well on garlic. When I ran out and forgot is when the cocci, fowl pox, and everything else started. That's anecdotal, and probably a coincidence, but it makes sense to me.
