Never feed them to your chickens if you have any doubts. I don't, neither do I give them raw potato skins for the same reason, both members of a plant species called Solanum.Just when I thought it was time to tear out all the tomato plants, I noticed today that many have a bunch ready to pick. Now I have read that tomato greens are toxic but I have read many BYC threads where people are tossing the greens in the runs.... How can this be?
From Wikipedia:
Plant toxicity
Leaves, stems, and green unripe fruit of the tomato plant contain small amounts of the toxic alkaloid tomatine.[52] They also contain solanine, a toxic alkaloid found in potato leaves and other plants in the nightshade family.[53][54] Use of tomato leaves in tea (tisane) has been responsible for at least one death.[52][53] However, levels of tomatine in foliage and green fruit are generally too small to be dangerous unless large amounts are consumed, for example, as greens. Small amounts of tomato foliage are sometimes used for flavoring without ill effect, and the green fruit is sometimes used for cooking, particularly as fried green tomatoes.[52] Compared to potatoes the amount of solanine in green or ripe tomatoes is low; however, even in the case of potatoes while solanine poisoning resulting from dosages several times normal human consumption has been demonstrated, actual cases of poisoning resulting from excessive consumption of potatoes that have high concentration of solanine are rare.[54]
Tomato plants can be toxic to dogs if they eat large amounts of the fruit, or chew plant material.[55]
Hope this helps. Another no-no is avocados. Chickens don't always know what is good or bad for them and will try anyhting.
