I have some 4 1/2 week old chicks that I would like to give some leftover parsley to, but I'm not sure if it's OK for them. I did a search, but couldn't find any difinitive yes or no answers.
Well, I guess since no one's said "Oh, Dear God, no... don't feed them parsley!", then I guess it's OK.
I feed them pretty much any green I've got leftover (and some fresh from the produce aisle), with the exception of some big no-no's like tomato greens and "green" potato peels. They eat what they want and don't eat some stuff. So I trust their judgment. That can get you in trouble sometimes, though, I hear.
I just gave mine parsley and they loved, it, plus it does have some vit's in it don't remember what though. i just cut up in to smaller pieces for them so they don't have a hard time eating it.
