The Chicken Chick has a couple of myths and facts on chicken treats [http://www.communitychickens.com/top-5-myths-and-facts-about-treats-for-chickens/] in which she mentions:
"Chickens can eat the flesh of avocado. However, avocado pits and skin contain persin, which can be toxic in significant quantities." and
"Chickens can eat onions, chives and garlic in small quantities, occasionally. Sufficient quantities of onion and garlic can be harmful to chickens, causing hemolytic anemia, aka: Heinz anemia, a blood condition resulting in chickens with weak legs, listlessness and a disheveled appearance. Bottom line: if I’m not going to eat a bowl of raw onions, chives or garlic, I’m not going to feed it to my chickens as a side dish."
