I have no idea, was just suggesting that you should google it. I happen to know that Garli is on toxic list, so I said something about it. FWIW, I'm not very good at beating around the bush, so if I thought you were about to feed something toxic, I wold say it, I would not tell you to google it.

I had checked a list just the other day and didn't see garlic on it. I saw onions, but not garlic so I thought it was alright. It was a list of plants toxic to chickens. I knew some of them already, others were surprising. Now, some were rated on toxicity and the majority were low on the list so I imagine it has much to do with how much is consumed.
